Thanks Peter! It’s as simple as I can put it I guess! Monitor and nurture if you can’t afford a lockup kit or a trans cooler like myself haha 😂 thanks Peter
spot on Keelan. I learned long ago that when when driving a Prado in Vic High Country you must keep it in low range - if you don’t the red light for transmission overheating lights up quick smart.
Keep up the good work, I have used a scanguage for the last 10years and 150,000klm of towing 2.5 ton, a must have plus I have an engine guard cylinder head adjustable temp alarm to alert you to a blown radiator hose that your coolant temp won’t register with rapid coolant loss.
I knew the info you said from work life but I've never seen it on a video before, good work Keelan (good camera work Sarah). Lovely background views of Ardrossan silos too!
Good write up I agree never tow in over drive gears, as you said they are the weakest gears, even with my lockup kit I would tow only in 4th. I'm no expert but here are a few things I've worked over the years I have the Richards after market lock up kit, I luv it It has high speed lock up and low speed lock up buttons High speed lock up in your case would work on 4th and 5th gear lock up Low speed lock up, locks up 1st, 2nd and 3rd gear, this a great for those long windy up hill sections of road, keeps the trans cool and engine is happy too. Something a lot of people down realise is using a lower gear to hold you back going down hills heats up the trans too, anytime there is slip in the trans there is heat build up, the aftermarket kit helps here too. Low speed will also lock up in low range, so great for keeping the temps down in the soft sand Something I found I interesting is even when locked up with the kit the trans will change gears, if you have it in 4th locked up and you come to a steep hill it will change down a gear and then lock up in that gear (if in low lock up) if in high lock up it changes down to 3rd and unlocks. Economy is better too, when unlocked the transmission is slipping and using more fuel
Thanks Neil! For sure mate the lockup kit a massive tick in my books. Even though I don’t have one I’ve always wanted one but could never afford it! One day I’ll have one haha For sure the torque converter unlocks down hills even though there’s no physical load. The engine will still try and slow the trailer down unlocking the converter and causing heat! Your right and not many people know that! Thanks for the comment mate 100% agree with your points!!
Your not wrong about Toyota's hunting for gears. I have the 1GD variant and yeah no chance of lock up in 5th even though it is a 6 speed. Tow in 4th also. I need a Scan gauge and put your theory to the test. Best explaination I have seen yet mate well done 🍻
Excellent advice! May I add a further thing that I do in my 200 Series. When towing I essentially drive it as a clutchless manual keeping revs between 2300 and 2600 regardless of road speed. I recently did a trip in western NSW on a dirt road. The road was such that I averaged about 55 km/h driving mainly in S3. Fuel economy 20.7 l/100km. Usually it is 22 to 25 l/100km.
Good information mate. I have a 2013 Prado Auto. 150000kms and it has just cracked a piston a month before we are due to get our van. Good times!.. I’ve had it since 9000kms well maintained and has only towed 500kgs for minimal kms. Disappointed is an understatement.
Mate that is such bad news! That is my worst nightmare! I dare say either a glow plug tip has snapped off or the injector seat is buggered and has leaked in the oil gallery and boom! I seriously feel for ya! Especially because you’ve had it since pretty much new and looked after it.. and the timing with the van. Spewing mate
@@SarahandKeelanTravels Yeah it’s placed us in a pretty crap position but we’ll get through it. On the piston situation, it is a known issue by Toyota with the 1KD-FTV engine. The pistons, especially the Euro 4 version all crack in the same spot across the top inline with the gudgeon pin. It’s a mechanical design flaw that Toyota addressed unsuccessfully 4 times. Not trying to scare you lol but have a read if you haven’t heard about it. It doesn’t happen to everyone but it has happened to that many now it should have been addressed by Toyota. The service bulletin is EG-008T-0112. I’ve had to buy another car to buy me time. I’m going to pull Toyota on for good will warranty, it’s not good enough IMO.
@@SarahandKeelanTravels yeah I’ll get the prado goin and probably get rid of it. Shame, it’s been a good car, it’s a good size, never missed a beat until this major failure. Got all the gear on it to but yeah the van is gonna be right up and possibly over it’s tow limit anyway. Im thinking a V8 patrol for a game changer (never owned a Nissan) or possibly new V6 ranger-Everest when they come out. Love my Toyotas but TBH both 200 and 300 series are out of my price range now. Anyways safe travels guys, enjoying your content, keep living the dream! 🇦🇺🇦🇺
This is a great vid for anyone who does not do there research, very well done mate, Nissan 4.2 turbos blow their 5 gear if you tow heavy , top gear in most vehicles is the weakest, also add a extra oil cooler to your transmission it helps alot, keep up the vids great work from both of you.🤙
@@SarahandKeelanTravels Thanks Keelan, we will work something out when you are back in the west, Kalbarri or Onslow , we will make sure you catch fish, Cheers Rolly
Thanks Cameron! Glad you enjoyed the video! It’s a hard one to film because it’s easy to get carried away with the technical side! This is the easiest way I can explain it!
Hey Jay, no doubt mate! I run a scan gauge 2, that’s all I know so I can’t really comment on anything else! Thanks for letting everyone know they can save some cash! 🤙🏽🤙🏽🍻
In addition to my original post there is a trend in 4x4 circles to increase ground clearance with lift kits and fitting larger diameter tyres . Fitting the larger tyres will also add more stress on the transmission when towing and in an overdrive gear. You are effectively making all gears, and more importantly your top gear, taller. That’s why Speedo’s need recalibration when doing this mod.
100% agree! We love our bigger tyres as they make the car a lot more capable with very little effort but like you said it adds strain on other parts! We find anything touring, 4wding a compromise! Things always make other things worse and things always make other things better! It’s about balancing the things against the things haha cheers mate
Very well explained re mods to any aspect of driveline configuration. Wouldn't it be great if all the aftermarket businesses explained this to customers prior to fitting any mods?😂😂😂
Very well explained re mods to any aspect of driveline configuration. Wouldn't it be great if all the aftermarket businesses explained this to customers prior to fitting any mods?😂😂😂
Love the ultragauge, can set alarms for whatever you want too, such as high temps or low voltage. Also had an EGT gauge fitted to my 3.0L grenade patrol and like you said its about getting to know your car and what numbers are normal for it.
thank you so much. Didn't know why my tranny overheated. Using my 4th gear has worked great and watching my Tachometer to see when the torque converter unlocks
Thanks Cindy! If you stick to the rules of spoken about and your within your weight regs you’ll have no issues what so ever!! Get a scan gauge first and foremost!! 🤙🏽🤙🏽🤙🏽🍻
I use two air trans coolers with fans and the factory one as well, so 3 all up and a larger transmission pan extra 1.5 Lt oil and tow 3ton. Temp never exceed 85’c, up hills in sand flat out and 38’ days. If it shutters it’s fukt just a little bit, it’s the start of major dramas 6k +. I change oil every 40k with filter. Or just get good insurance.
@@SarahandKeelanTravels New car warranty fixed it once, now I’ve made it last. Better yet, buy a chev. Stay away from small trucks like yours towing, your still in a state with no hills, better you invest some money into more power because you will only do 1 lap. (What’s the point)
Keegan you are the bloodily legend mate! Awesome video bro I got so much out of it! Hope you put some more of those mechanical style advice videos together. Awesome job mate, cheers 🍺🍺🍺
Great video. I was aware of the need to keep temps in check but hadn't realised just how quickly temps would escalate under "normal" driving conditions. 20sec and you had gone from safe to knocking on door of temps that would degrade the oil.
That’s right mate! I can’t make it more clear than to show you in real time what happens!! First thing is monitoring! Being aware and understand how the car behaves under conditions and then if you have the money which I do not haha buy a lockup kit or trans cooler and or both but I can afford it at the moment so will stick to 4th gear and taking it easy haha
Good video guys. I use an OBDII scanner to monitor all those numbers while towing and provide alerts. As you have shown it is not difficult to slightly modify your driving style to suit conditions and reduce strain on your driveline when you can see these numbers and find the "sweet spot"
Good video mate, agree with most of what you had to say, but bottom line really is if your gonna tow, fit an external transmission cooler.....its a no brainer....made about a 10 to 12 degree reduction in our BT50 pulling 3.3t caravan around the island....
Thanks Graham! For sure mate! For me I wasn’t 100% educated on the coolers so that’s why I didn’t mention! I was aware of them but when you don’t know your topic then it’s best not to mention! After looking into them they look like the way to go! I personally can’t afford one so I’ll stick to just taking it easy, monitoring and driving accordingly
great video and very useful information thank you, we leave on July 4th to the Kimberley and all the way around and back to the Gold Coast, 2 months this first trip then wifey flies home from Uluru and I head up to Katherine and across pretty much on the same trail but I will be good prospecting alone for 3 months then I head home before Christmas 😁, I also have a 2010 150 series with around $35k of extras on it, I just fitted the trans oil cooler and will put the scan tool on this week. Cheers guys maybe I’ll see you on the road one day 😁
Hey Jason glad you got something out of the video!! Thanks for the support! Ripper trip by the sounds of it and I hope you find some goodies!! For sure mate give us a hoot if you ever see us! 🍻🤙🏽🤟🏻
definitely will say hi if we see you on our travels, we own gold leases in the goldfields around coolgardie to Leonora areas, you’re welcome to come camp up and have a detect when we are there, we have spare detectors 😊
gday guys, we have done the trip now and made it back in one piece, I monitored the trans temp like a hawk, I spoke to Prado owners who totally baked their trans oil and had no gear changes at all, I mentioned what I had done and I pretty much got told I don’t know anything, my temp sat on 80 in 4th all day every day, love the Prado 😁
Hey Andrew cheers mate! I think a cooler is a must if your constantly trying to tow the 100kmh even in strong head winds.. but we just cruise mate! I listen to the car and monitor the temps and I back off it’s Percy isn’t loving it! Keep her running in the sweet spot!
I guess I don't really need to buy the Scangauge as you've done the testing, and the message is to not use overdrive gears when towing. I have a Pajero Sport with 8 gears. 7 and 8 are overdrive. When not towing I use full automatic. When towing I tend to drive in 6 when under any load, 5 with steeper inclines, 7 when declining (is that the right word?) and 8 not at all. Some vehicles will change their behaviour when towing, but the PS doesn't seem to. I tend to look at the tacho and keep the revs around 2000 or more when towing.
Excellent video Keelan. Your mate Derek overdone heated his Ranger trans in Queensland. Too bad he didn't have your knowledge at the time. Has the 79' now, is that a manual? You keep surprising with your knowledge in general for a young bloke. Is the wine as good as home mate? I like SA wine. Marg R is best in the world though. I'm biased 😆
Thanks mate!! 🤙🏽 yeah he did haha 😂 that’s one story that I’m referring to in this! His 79 is manual! It’s a really good tow rig in my opinion! Haha wine is good but I’m biased too haha 😂 been having a lot of fun up in the Barossa! Cheers Malc!
Good vid mate, Coulda maybe touched on trans coolers - running up grades and regular checks / services help too. Are you running a stock cooler? Nice yorkes. Love it!
Cheers Steven! For sure mate, trans cooler and lockup would be the go!! Like I said it was just basic info though, being able to monitor the temps is most important and there are ways to manage it. We have stock everything and I just monitor it, tow in 4th an drive at a speed (90-95km) that it allows me to lock in the TC and control my temps. Normally sits on 80 degrees TC and trans temp when in the 1:1 ratio.
@@SarahandKeelanTravels yer sweet enjoy the weather i think we have 30c this wk end. If ys head south of adl. Check out deep creek. Cape jervis. Maybe KI. Victor harbor. Good surf at victor mate. Victor / middleton and good bakerys lol
Whilst observing EGT's and auto transmission temps is a good thing, its something completely different to actually understand what the numbers mean. With EGT's your not looking at the peak number, your looking at consistancy, and variantions within that figure, EGT's can vary quite wildly, if you are using an aftermarket probe, moving it even 4-5cm can see temp differences of 50-80c. As for Auto temps, auto boxes are good for 130c fluid temp constant, but they also rely on not running too cold, you will find most auto's these days have a thermostat within the auto which restricts fluid movement until a set temp as part of the cold temp warmup, so seeing temps
Hey Daniel! 100% on the EGTs in terms with the trans temps I have read and heard similar things about specific cars and auto boxes however like I stated this is a basic video explaining in a way that average jo blows with limited towing/ auto experience can comprehend. In terms with not seeing fluid movement until past 90 degrees is subject to change from car to car. For my Prado I would take sub 90 degrees for a long period of time over 110 degrees for a long period of time. So you reckon if you only service/change auto fluid as per the user manual (could be 6 months depending on car) and everyday you punish cough* I mean drive your car plus tow 2.5t for hours and hours like we do whilst your trans temp is 130degrees constant your fine and nothing will happen!? 😂😂 the box might be rated to 130 degrees but I can guarantee the molecular makeup/ viscosity/ and every principle that makes that fluid effective will be lost after after a month of your punishment 😂😂 the trans temp light will be flashing red on the dash but you reckon keep driving? Right
@@SarahandKeelanTravels Agree with you. Gearboxes are happiest in the 80’s temp range. With auto gear boxes that have multiple clutch packs that rely on friction to maintain power transmission, any increase in temperature above 100 c for extended times usually means you are having some serious slipping going on. Heat is generated in an auto in two main areas : torque converter as it relies on transmission fluid to transmit torque, slipping is part of the process therefore the the fluid heats up. Clutch packs are used to provide the different gear ratios on the epicyclic gear sets and lock the torque converter. Any damage to these clutch packs will cause slipping and generate heat.
I agree with your comments Daniel. I’m sure that transmissions and transmission fluids of yesteryear were designed to not exceed lower temperatures, but now they are. I always find it amusing too, that any claims that coolers need to be fitted or fluids need to be constantly replaced, usually come from transmission repair companies. I’m pretty sure that modern vehicle design engineers aren’t fools.
@@petep7410 people saying lower temps are better seem to be oblivious that you only need to look at the cars cooling system and the fact they run thermostats to help the motor warm up and keep it running within a certain temperature range. Auto transmissions are no different, they like their set temp range which is typically 95-120c and many auto temps including popular models like the ranger have thermostats within the transmission itself, to allow it to warm up faster and maintain that minimum operating temp.
Hey, Keelan, I thought you said sometime that you EGT on your ScanGuage, if you do, where can I find the code. I have the same model Prado as you. Cheers Mate. Great vids.
Thankyou!! Glad you enjoyed it! No we don’t as I like to be on the safe side however I know people who do and don’t seem to have issues! Varys from car to car though that’s the only issue! If your asking me then I reckon maybe not
@@smelltheroses7267 no don’t use cruise control while towing heavy loads. Read your user manual carefully on towing. Most 4x4 makers will advise not use cruise control.
Hey mate! Cheers, It all depends on your speed. We had hard time keeping torque converter temp down on the Gibb simply because we could hit the speed threshold in 4th gear to lock the torque converter up, (typically 68-80kmh) if your planning doing a lot of corrugations maybe look into a trans cooler and a lockup kit! But if not I would say select manual 4th gear still make sure you can monitor your temps and just find the sweet spot where your TC temps arnt staying over 100degrees for long periods of time and if so pull over and take a break every now and again! Your shock absorbers will thank you for the rest stops too!

Informative video and should help a lot of people avoid cooking their auto transmission. Also pays for owners to confirm which gears are overdrive. If you have an 8 speed gearbox you will probably find gears 7 and 8 are overdrive, so you should not go higher than 6. Also avoid the temptation of using cruise control..
Thanks Fred! 100% agree with your statement! Should of stated that however that’s where my knowledge of trans boxes finishes I know up to 6/7 speeds and I don’t like commenting if I’m not 100% if I’m right or not! Thanks mate great point
@@SarahandKeelanTravels yeah I think the the 6 speed box has overdrive on 5 and 6. Interesting the manual 6 speed is overdrive only in 6. The manual would make a better towing vehicle.
saw TCLUK in the the desc, havent even watched it yet, but had to comment hah!! I have a 200 series, got a lock up kit, trans remap and engine remap/tune done in Perth in 2017 on my first half aus lap. Towing a 17 foot van at 2.2 tons. By the time i got to Broome, it had paid for it self in fuel savings. Let alone trans temp reduction. Hunting for the correct gear vs revs was also almost gone. I realise mines the 4.5 liter v8, and kitted a bit, however, i still think any one towing in an auto should invest in a lock up kit. No matter what brand of vehicle, the benefits out weigh the costs by a huge margin. I have an UltraGuage and trans temps is one of the windows set in the shit i like to see, turn off the luk when towing, watch the temps go through the roof, turn it back on... back down 30-40 C lower. Ill go watch your episode now. G.
Cheers mate haha have a watch haha you pretty much covered everything I said haha! 100% agree though! The reason I havnt got a lockup kit is because I can’t afford one haha but I strongly suggest them to a lot of people! If you can get one the being able to monitor and drive accordingly is the next best thing!
We always run sports mode which is S4, throwing into drive and letting the cars computers decide the shifts will heat up your trans in high gear as the TC won’t lock up
@@SarahandKeelanTravels, Cheers guy for the Info, we have a 2021 LC200 So we can relate to what you said about the gears changing up and down even without a load behind it. We have done a lockup kit through SQP, have a look at what they do there are no switches to turn on or off he does it through the computer side of it interesting. We can't wait to be on the road full-time ourselves, Love watching you guys travel around, and your tips and tricks.
look up wholesale automatic transmissions ask orto and see if he does a torque converter lock up mod . oh right yeah u just said it now at the end .. cool.
Just out of interest what does Toyota recommend? When I contacted Isuzu about towing in our MU-X they specifically told me not to hold gears manual and to only ever tow in auto. Also I think fitting an auto trans cooler on vehicles that to is always a good idea.
Im sure If you ask your manufacturer in there humble opinion they have made the perfect vehicle and you shouldn’t need to fit any mods or drive it any way. It says i can tow 3t on the user manual so I can slap it into drive and tow 3t. Unfortunately that’s where many people are getting caught out melting there Torque converter or over heating there transmission. In regards to holding gear, they may of been referring to holding it in your overdrive gear. But holding it in a higher rev range and a stronger lower gear is a lot better for a vehicle then letting the car hunt gears constant unlocking the torque converter and heating up the trans the TC and the engine. I agree on the trans cooler!
@@SarahandKeelanTravels actually my dealer is pretty honest about the flaws (crazy I know!) he told me about the dodger turbos and the thin paint, and admitted that they benefit from a catch can to prevent build up. He did say the trans was pretty rock solid though. We tow a 2.2t maverick camper and have had no problems yet. Ultra gauge in order though just to be able to keep an eye on things!
I would 100% advocate for holding you top gear that’s not over drive which for me is 4th, not sure what the MUx has but I’m sure it’s equally as bulletproof and like you said ultra gauge or any gauge you can keep an eye on it. Once you get your gauge and tow a bit you’ll see how the cars temps behave on hills ect. Play around with it! Slap it into overdrive and watch the temps go up and down with speed and when the TC locks and unlocks! You’ll learn pretty quickly what the car likes and dosnt like!! Few hills around Adelaide are testing Percy the Prado out lately haha 😂
I'm a motor mechanic and honestly I could not have explained that any where near as good as you did and you were driving at the same tme, you must ave a few female genes.
Hahah thanks mate!! It’s hard not to use the crazy technical terms! Appreciate the feedback!! Funny that because I can’t multi task to save myself 🤙🏽🍻😂😂
Higher rpm _is_ correlated with higher fuel consumption because the engine is an air pump - the faster it spins, the harder it has to work to suck fresh air in and push hot exhaust out. Thermal efficiency tends to be greatest at a moderate rpm and tapers off at the extreme lows and highs.
I find that my 6 speed electronic controlled gear box is a lot smarter than me it has instant access to all the required sensors so I let it make all the decisions Holding a gear could put unknown stress on mechanical parts But I take your opinion on board as your experience is of great value
100% false mate. This is exactly what the 6 odd people that cooked there transmissions in brand new “smart cars” said to us. Generally Your car will only tell you (dash light) that your trans is too hot once your in the zone to break things. Transmission fluids arnt designed to stay at 120 plus degrees for extended periods of time. After a while the viscosity of the fluid is effected and the very principles that makes that specific fluid good for COOLING your transmission is now compromised because your waiting for a dash light to tell you when to back off. Do that day in day out and your looking at a massive towing bill, a new transmission and a canceled holiday. I’ve done extensive research plus I’ve heard the horror stories to back up what I’m saying. Hope I have persuaded your opinion haha thanks Arthur
You are right, the box is really good at selecting the "right" gear. But it isn't smart. It is programmed. Do you think that maintaining optimum temp under heavy load at the expense of smooth shifting and economy when not under load was the programmers goal? What sells cars, transmission temps or a ridiculously low fuel consumption figure in the marketing brochure and a nice test drive? The vast majority of common tow vehicles like Prados and DC utes are NOT ised to tow heavy loads for long distance at high ambient temps. Why would the manufacturer prioritise the transmission shift protocols for a minority of buyers?
@@SarahandKeelanTravels ...I drive a 2019 Holden Colorado I did add a transmission cooler but basically leave it on drive and keep checking the transmission temp and stays pretty cool (68 to 78 degC) apparently up the hills it changes down with little sense of slippage and down the hills it does a great job at engine breaking, if your on the brake a bit the gearbox drops down a gear and locks, apparently the Colorado has one of the smartest transmission on the market, l just did the Great Alpine Road from Omeo to Bright (around Mt Hotham 1825m altitude, one of the highest roads in Aus) towing a caravan 1700 kgs not a super heavy one but the 6 speed auto puts a smile on your face...I did stop for a while on the way down to cool the caravan brakes but one of the most scenic routes with a great free camp in Omeo and another in Smoko before Bright
@@SarahandKeelanTravels so when I go full throttle does it still lock up. I seen somewhere that says almost all torque converters don’t lock up at full throttle
Great to hear someone explain in simple terms “ mechanical sympathy” they need to be nurtured or they will go bang. Good job Keelan 👏👏👍
Thanks Peter! It’s as simple as I can put it I guess! Monitor and nurture if you can’t afford a lockup kit or a trans cooler like myself haha 😂 thanks Peter
spot on Keelan. I learned long ago that when when driving a Prado in Vic High Country you must keep it in low range - if you don’t the red light for transmission overheating lights up quick smart.
Cheers Robert! Bingo mate! Sounds like you have the experience and the knowledge to match! I’ve done the same thing haha 😂
Keep up the good work, I have used a scanguage for the last 10years and 150,000klm of towing 2.5 ton, a must have plus I have an engine guard cylinder head adjustable temp alarm to alert you to a blown radiator hose that your coolant temp won’t register with rapid coolant loss.

Great advice mate
Also trans fluid change, don’t believe the manufacturers that tell you it doesn’t need changing 👍
Thanks mate Hahah yeah changed mine when we were back home for a bit! I 100% agree haha
This was the info I’ve been looking for. Thank you. Great vids as always
Good write up
I agree never tow in over drive gears, as you said they are the weakest gears, even with my lockup kit I would tow only in 4th.
I'm no expert but here are a few things I've worked over the years
I have the Richards after market lock up kit, I luv it
It has high speed lock up and low speed lock up buttons
High speed lock up in your case would work on 4th and 5th gear lock up
Low speed lock up, locks up 1st, 2nd and 3rd gear, this a great for those long windy up hill sections of road, keeps the trans cool and engine is happy too.
Something a lot of people down realise is using a lower gear to hold you back going down hills heats up the trans too, anytime there is slip in the trans there is heat build up, the aftermarket kit helps here too.
Low speed will also lock up in low range, so great for keeping the temps down in the soft sand
Something I found I interesting is even when locked up with the kit the trans will change gears, if you have it in 4th locked up and you come to a steep hill it will change down a gear and then lock up in that gear (if in low lock up) if in high lock up it changes down to 3rd and unlocks.
Economy is better too, when unlocked the transmission is slipping and using more fuel
Thanks Neil! For sure mate the lockup kit a massive tick in my books. Even though I don’t have one I’ve always wanted one but could never afford it! One day I’ll have one haha
For sure the torque converter unlocks down hills even though there’s no physical load. The engine will still try and slow the trailer down unlocking the converter and causing heat! Your right and not many people know that!
Thanks for the comment mate 100% agree with your points!!
I just commented above, same richards here in my 200 series.
Your not wrong about Toyota's hunting for gears. I have the 1GD variant and yeah no chance of lock up in 5th even though it is a 6 speed. Tow in 4th also. I need a Scan gauge and put your theory to the test. Best explaination I have seen yet mate well done 🍻
Yeah right, wasnt 100% sure on the gearing so I didn’t comment! Thanks mate appreciate you support and yes get a scangauge
In the 6 speed transmission for the GD, 4th gear is still 1:1 and there are two overdrive gears.
Excellent advice! May I add a further thing that I do in my 200 Series. When towing I essentially drive it as a clutchless manual keeping revs between 2300 and 2600 regardless of road speed.

Im thinking a V8 patrol for a game changer (never owned a Nissan) or possibly new V6 ranger-Everest when they come out. Love my Toyotas but TBH both 200 and 300 series are out of my price range now. Anyways safe travels guys, enjoying your content, keep living the dream! 🇦🇺🇦🇺
This is a great vid for anyone who does not do there research, very well done mate, Nissan 4.2 turbos blow their 5 gear if you tow heavy , top gear in most vehicles is the weakest, also add a extra oil cooler to your transmission it helps alot, keep up the vids great work from both of you.🤙
Thanks mate!! Cheers for that tip too! I’m pretty familiar with the lockup kits but I need to do more research into the coolers! Cheers
well covered Keelan, i tow a 3-5 ton boat with a 79 series and never tow in fifth gear and have a scan gauge and a pillar pod to watch the egt's
Thanks Rolly! Sounds like you need to take me fishing mate haha 😂
Good setup mate! Perfect I reckon!
@@SarahandKeelanTravels Thanks Keelan, we will work something out when you are back in the west, Kalbarri or Onslow , we will make sure you catch fish, Cheers Rolly
No worries mate!! 🤙🏽🤙🏽🤙🏽🍻
Best information I’ve heard on this subject ever. Well done and very informative. Need a discount code for a scan gauge now.
I use a $20 Bluetooth dongle and the paid torque pro app.. can do a lot more with that. Works a treat.
Thanks Cameron! Glad you enjoyed the video! It’s a hard one to film because it’s easy to get carried away with the technical side! This is the easiest way I can explain it!
Hey Jay, no doubt mate! I run a scan gauge 2, that’s all I know so I can’t really comment on anything else! Thanks for letting everyone know they can save some cash! 🤙🏽🤙🏽🍻
In addition to my original post there is a trend in 4x4 circles to increase ground clearance with lift kits and fitting larger diameter tyres . Fitting the larger tyres will also add more stress on the transmission when towing and in an overdrive gear. You are effectively making all gears, and more importantly your top gear, taller. That’s why Speedo’s need recalibration when doing this mod.
100% agree! We love our bigger tyres as they make the car a lot more capable with very little effort but like you said it adds strain on other parts! We find anything touring, 4wding a compromise! Things always make other things worse and things always make other things better! It’s about balancing the things against the things haha cheers mate
@@SarahandKeelanTravels Agree it’s all about being aware that changes to OEM specifications can introduce unwanted consequences.
Very well explained re mods to any aspect of driveline configuration. Wouldn't it be great if all the aftermarket businesses explained this to customers prior to fitting any mods?😂😂😂

Great information must look into for my 2021 Ranger Bi Turbo hope I can come down and see you on Sunday
For sure mate! Happy to talk more about it with you this Sunday!! Come down and say Gday!
Great info mate, well done.
Keep up the great content guys.
Those waves were sick last week, you were ripping.
Thanks John! Cheers mate!
Perfect waves! Probably some of my favourite waves ever surfed! The waves made me look good
Love the ultragauge, can set alarms for whatever you want too, such as high temps or low voltage. Also had an EGT gauge fitted to my 3.0L grenade patrol and like you said its about getting to know your car and what numbers are normal for it.
Ultra gauge is a great product from what I gather! Haha the old Granada haha 😂 for sure mate 100% agree! Every car is different and behave differently
After fitting an EGT gauge to my Prado for towing, I agree on everything you said.
I’m sure you were surprised on just how hot them EGTs can get!! I wish I could monitor mine! Just another splash of cash on my money pit haha 😂
@@SarahandKeelanTravels ha ha money pit is the correct terminology when referring to common rail diesel :)

thank you so much. Didn't know why my tranny overheated. Using my 4th gear has worked great and watching my Tachometer to see when the torque converter unlocks
Good info I’m going to get a second hand prado this year to tow my van
Thanks Cindy! If you stick to the rules of spoken about and your within your weight regs you’ll have no issues what so ever!! Get a scan gauge

I use two air trans coolers with fans and the factory one as well, so 3 all up and a larger transmission pan extra 1.5 Lt oil and tow 3ton. Temp never exceed 85’c, up hills in sand flat out and 38’ days. If it shutters it’s fukt just a little bit, it’s the start of major dramas 6k +. I change oil every 40k with filter. Or just get good insurance.
Some good info here mate! Sounds like you have a good setup! 85c is perfect
@@SarahandKeelanTravels
New car warranty fixed it once, now I’ve made it last. Better yet, buy a chev. Stay away from small trucks like yours towing, your still in a state with no hills, better you invest some money into more power because you will only do 1 lap. (What’s the point)
Keegan you are the bloodily legend mate! Awesome video bro I got so much out of it! Hope you put some more of those mechanical style advice videos together. Awesome job mate, cheers 🍺🍺🍺
Thanks mate! Glad you enjoyed it! I’ll keep that in mind and see if I can’t think of a few more beneficial ones! Thanks legend 🤙🏽🤙🏽
Great video. I was aware of the need to keep temps in check but hadn't realised just how quickly temps would escalate under "normal" driving conditions. 20sec and you had gone from safe to knocking on door of temps that would degrade the oil.
That’s right mate! I can’t make it more clear than to show you in real time what happens!! First thing is monitoring! Being aware and understand how the car behaves under conditions and then if you have the money which I do not haha buy a lockup kit or trans cooler and or both but I can afford it at the moment so will stick to 4th gear and taking it easy haha
Good video guys. I use an OBDII scanner to monitor all those numbers while towing and provide alerts. As you have shown it is not difficult to slightly modify your driving style to suit conditions and reduce strain on your driveline when you can see these numbers and find the "sweet spot"
Great setup John! That’s right mate I 100% agree with you!
Good video mate, agree with most of what you had to say, but bottom line really is if your gonna tow, fit an external transmission cooler.....its a no brainer....made about a 10 to 12 degree reduction in our BT50 pulling 3.3t caravan around the island....
Thanks Graham! For sure mate! For me I wasn’t 100% educated on the coolers so that’s why I didn’t mention! I was aware of them but when you don’t know your topic then it’s best not to mention! After looking into them they look like the way to go! I personally can’t afford one so I’ll stick to just taking it easy, monitoring and driving accordingly
great video and very useful information thank you, we leave on July 4th to the Kimberley and all the way around and back to the Gold Coast, 2 months this first trip then wifey flies home from Uluru and I head up to Katherine and across pretty much on the same trail but I will be good prospecting alone for 3 months then I head home before Christmas 😁, I also have a 2010 150 series with around $35k of extras on it, I just fitted the trans oil cooler and will put the scan tool on this week. Cheers guys maybe I’ll see you on the road one day 😁
Hey Jason glad you got something out of the video!! Thanks for the support! Ripper trip by the sounds of it and I hope you find some goodies!! For sure mate give us a hoot if you ever see us! 🍻🤙🏽🤟🏻
definitely will say hi if we see you on our travels, we own gold leases in the goldfields around coolgardie to Leonora areas, you’re welcome to come camp up and have a detect when we are there, we have spare detectors 😊
No worries legends! We are a bit far away! East of Adelaide but for sure if we were in WA thanks and appreciate the offer 🤙🏽🤙🏽
gday guys, we have done the trip now and made it back in one piece, I monitored the trans temp like a hawk, I spoke to Prado owners who totally baked their trans oil and had no gear changes at all, I mentioned what I had done and I pretty much got told I don’t know anything, my temp sat on 80 in 4th all day every day, love the Prado 😁
Great information mate, a transmission cooler is a must for towing
Hey Andrew cheers mate! I think a cooler is a must if your constantly trying to tow the 100kmh even in strong head winds.. but we just cruise mate! I listen to the car and monitor the temps and I back off it’s Percy isn’t loving it! Keep her running in the sweet spot!
@@SarahandKeelanTravels same mate, no point rushing things
Haha Narh plenty of time for us lucky buggers aye! 🤙🏽🤙🏽😂
I guess I don't really need to buy the Scangauge as you've done the testing, and the message is to not use overdrive gears when towing. I have a Pajero Sport with 8 gears. 7 and 8 are overdrive. When not towing I use full automatic. When towing I tend to drive in 6 when under any load, 5 with steeper inclines, 7 when declining (is that the right word?) and 8 not at all. Some vehicles will change their behaviour when towing, but the PS doesn't seem to. I tend to look at the tacho and keep the revs around 2000 or more when towing.
Nice video bro very informative 😎 👍
Thanks legend
Bang on bit of info!👍

Good vid mate, Coulda maybe touched on trans coolers - running up grades and regular checks / services help too. Are you running a stock cooler? Nice yorkes. Love it!
Cheers Steven! For sure mate, trans cooler and lockup would be the go!! Like I said it was just basic info though, being able to monitor the temps is most important and there are ways to manage it. We have stock everything and I just monitor it, tow in 4th an drive at a speed (90-95km) that it allows me to lock in the TC and control my temps. Normally sits on 80 degrees TC and trans temp when in the 1:1 ratio.

Whilst observing EGT's and auto transmission temps is a good thing, its something completely different to actually understand what the numbers mean. With EGT's your not looking at the peak number, your looking at consistancy, and variantions within that figure, EGT's can vary quite wildly, if you are using an aftermarket probe, moving it even 4-5cm can see temp differences of 50-80c. As for Auto temps, auto boxes are good for 130c fluid temp constant, but they also rely on not running too cold, you will find most auto's these days have a thermostat within the auto which restricts fluid movement until a set temp as part of the cold temp warmup, so seeing temps
Hey Daniel! 100% on the EGTs in terms with the trans temps I have read and heard similar things about specific cars and auto boxes however like I stated this is a basic video explaining in a way that average jo blows with limited towing/ auto experience can comprehend.
In terms with not seeing fluid movement until past 90 degrees is subject to change from car to car. For my Prado I would take sub 90 degrees for a long period of time over 110 degrees for a long period of time. So you reckon if you only service/change auto fluid as per the user manual (could be 6 months depending on car) and everyday you punish cough* I mean drive your car plus tow 2.5t for hours and hours like we do whilst your trans temp is 130degrees constant your fine and nothing will happen!? 😂😂 the box might be rated to 130 degrees but I can guarantee the molecular makeup/ viscosity/ and every principle that makes that fluid effective will be lost after after a month of your punishment 😂😂 the trans temp light will be flashing red on the dash but you reckon keep driving? Right
Have a read of this Daniel, everything I’ve stated is backed up in this
thetransmissioncentre.com.au/?page_id=105
@@SarahandKeelanTravels Agree with you. Gearboxes are happiest in the 80’s temp range. With auto gear boxes that have multiple clutch packs that rely on friction to maintain power transmission, any increase in temperature above 100 c for extended times usually means you are having some serious slipping going on. Heat is generated in an auto in two main areas : torque converter as it relies on transmission fluid to transmit torque, slipping is part of the process therefore the the fluid heats up. Clutch packs are used to provide the different gear ratios on the epicyclic gear sets and lock the torque converter. Any damage to these clutch packs will cause slipping and generate heat.
I agree with your comments Daniel. I’m sure that transmissions and transmission fluids of yesteryear were designed to not exceed lower temperatures, but now they are. I always find it amusing too, that any claims that coolers need to be fitted or fluids need to be constantly replaced, usually come from transmission repair companies. I’m pretty sure that modern vehicle design engineers aren’t fools.
@@petep7410 people saying lower temps are better seem to be oblivious that you only need to look at the cars cooling system and the fact they run thermostats to help the motor warm up and keep it running within a certain temperature range. Auto transmissions are no different, they like their set temp range which is typically 95-120c and many auto temps including popular models like the ranger have thermostats within the transmission itself, to allow it to warm up faster and maintain that minimum operating temp.
Investigate 4X4MM lockup kit, the problem you describe goes away, transmission has less wear, and save fuel, all at the same time.
Thanks mate I will have a look now
Hey, Keelan, I thought you said sometime that you EGT on your ScanGuage, if you do, where can I find the code. I have the same model Prado as you. Cheers Mate. Great vids.
Hey mate that’s the only gauge I can’t get unfortunately, have trans temps but no EGT unfortunately. Sorry I can’t help
That was terrific info thank you. Dumb question, would you ever use cruise control while towing your van?
Thankyou!! Glad you enjoyed it! No we don’t as I like to be on the safe side however I know people who do and don’t seem to have issues! Varys from car to car though that’s the only issue! If your asking me then I reckon maybe not
@@SarahandKeelanTravels thanks very much 👍
@@smelltheroses7267 no don’t use cruise control while towing heavy loads. Read your user manual carefully on towing. Most 4x4 makers will advise not use cruise control.
@@frednurks8528 thank you 🙂👍
Great information, what gear would you use on bad corrugations ?
Hey mate! Cheers,
It all depends on your speed. We had hard time keeping torque converter temp down on the Gibb simply because we could hit the speed threshold in 4th gear to lock the torque converter up, (typically 68-80kmh)
if your planning doing a lot of corrugations maybe look into a trans cooler and a lockup kit! But if not I would say select manual 4th gear still make sure you can monitor your temps and just find the sweet spot where your TC temps arnt staying over 100degrees for long periods of time and if so pull over and take a break every now and again! Your shock absorbers will thank you for the rest stops too!

No worries mate glad I can help! Cheers for the support
Informative video and should help a lot of people avoid cooking their auto transmission. Also pays for owners to confirm which gears are overdrive. If you have an 8 speed gearbox you will probably find gears 7 and 8 are overdrive, so you should not go higher than 6. Also avoid the temptation of using cruise control..
Thanks Fred! 100% agree with your statement! Should of stated that however that’s where my knowledge of trans boxes finishes I know up to 6/7 speeds and I don’t like commenting if I’m not 100% if I’m right or not! Thanks mate great point
@@SarahandKeelanTravels yeah I think the the 6 speed box has overdrive on 5 and 6. Interesting the manual 6 speed is overdrive only in 6. The manual would make a better towing vehicle.
Great info!
saw TCLUK in the the desc, havent even watched it yet, but had to comment hah!! I have a 200 series, got a lock up kit, trans remap and engine remap/tune done in Perth in 2017 on my first half aus lap. Towing a 17 foot van at 2.2 tons. By the time i got to Broome, it had paid for it self in fuel savings. Let alone trans temp reduction. Hunting for the correct gear vs revs was also almost gone. I realise mines the 4.5 liter v8, and kitted a bit, however, i still think any one towing in an auto should invest in a lock up kit. No matter what brand of vehicle, the benefits out weigh the costs by a huge margin. I have an UltraGuage and trans temps is one of the windows set in the shit i like to see, turn off the luk when towing, watch the temps go through the roof, turn it back on... back down 30-40 C lower. Ill go watch your episode now. G.
Cheers mate haha have a watch haha you pretty much covered everything I said haha! 100% agree though! The reason I havnt got a lockup kit is because I can’t afford one haha but I strongly suggest them to a lot of people!

Mate are you using it in Auto at the start when taking off or do you flip it over to S mode straight away and use it as a manual?
We always run sports mode which is S4, throwing into drive and letting the cars computers decide the shifts will heat up your trans in high gear as the TC won’t lock up
@@SarahandKeelanTravels, Cheers guy for the Info, we have a 2021 LC200
So we can relate to what you said about the gears changing up and down even without a load behind it. We have done a lockup kit through SQP, have a look at what they do there are no switches to turn on or off he does it through the computer side of it interesting. We can't wait to be on the road full-time ourselves, Love watching you guys travel around, and your tips and tricks.
look up wholesale automatic transmissions ask orto and see if he does a torque converter lock up mod . oh right yeah u just said it now at the end .. cool.
Haha thanks mate! 😂😂
Nice guys
Thanks Troy 🤙🏽🍻
How do u know when the torque converter is locked up??
You need a scan gauge mate, normally the revs will drop down suddenly and the car will have no slipping in the drive train
You no wear seat belt while driving?
have another watch Brian.. haha of course we do
Just out of interest what does Toyota recommend? When I contacted Isuzu about towing in our MU-X they specifically told me not to hold gears manual and to only ever tow in auto.
Also I think fitting an auto trans cooler on vehicles that to is always a good idea.
Im sure If you ask your manufacturer in there humble opinion they have made the perfect vehicle and you shouldn’t need to fit any mods or drive it any way. It says i can tow 3t on the user manual so I can slap it into drive and tow 3t. Unfortunately that’s where many people are getting caught out melting there Torque converter or over heating there transmission.
In regards to holding gear, they may of been referring to holding it in your overdrive gear. But holding it in a higher rev range and a stronger lower gear is a lot better for a vehicle then letting the car hunt gears constant unlocking the torque converter and heating up the trans the TC and the engine.
I agree on the trans cooler!
thetransmissioncentre.com.au/?page_id=105
@@SarahandKeelanTravels actually my dealer is pretty honest about the flaws (crazy I know!) he told me about the dodger turbos and the thin paint, and admitted that they benefit from a catch can to prevent build up. He did say the trans was pretty rock solid though. We tow a 2.2t maverick camper and have had no problems yet. Ultra gauge in order though just to be able to keep an eye on things!
I would 100% advocate for holding you top gear that’s not over drive which for me is 4th, not sure what the MUx has but I’m sure it’s equally as bulletproof and like you said ultra gauge or any gauge you can keep an eye on it. Once you get your gauge and tow a bit you’ll see how the cars temps behave on hills ect. Play around with it! Slap it into overdrive and watch the temps go up and down with speed and when the TC locks and unlocks! You’ll learn pretty quickly what the car likes and dosnt like!! Few hills around Adelaide are testing Percy the Prado out lately haha 😂
I'm a motor mechanic and honestly I could not have explained that any where near as good as you did and you were driving at the same tme, you must ave a few female genes.
Hahah thanks mate!! It’s hard not to use the crazy technical terms! Appreciate the feedback!! Funny that because I can’t multi task to save myself 🤙🏽🍻😂😂
Higher rpm _is_ correlated with higher fuel consumption because the engine is an air pump - the faster it spins, the harder it has to work to suck fresh air in and push hot exhaust out. Thermal efficiency tends to be greatest at a moderate rpm and tapers off at the extreme lows and highs.
Why do I get better fuel economy at 2500rpm then 1800rpm?
I find that my 6 speed electronic controlled gear box is a lot smarter than me it has instant access to all the required sensors so I let it make all the decisions
Holding a gear could put unknown stress on mechanical parts
But I take your opinion on board as your experience is of great value
100% false mate. This is exactly what the 6 odd people that cooked there transmissions in brand new “smart cars” said to us. Generally Your car will only tell you (dash light) that your trans is too hot once your in the zone to break things. Transmission fluids arnt designed to stay at 120 plus degrees for extended periods of time. After a while the viscosity of the fluid is effected and the very principles that makes that specific fluid good for COOLING your transmission is now compromised because your waiting for a dash light to tell you when to back off. Do that day in day out and your looking at a massive towing bill, a new transmission and a canceled holiday. I’ve done extensive research plus I’ve heard the horror stories to back up what I’m saying. Hope I have persuaded your opinion haha thanks Arthur
You are right, the box is really good at selecting the "right" gear. But it isn't smart. It is programmed. Do you think that maintaining optimum temp under heavy load at the expense of smooth shifting and economy when not under load was the programmers goal? What sells cars, transmission temps or a ridiculously low fuel consumption figure in the marketing brochure and a nice test drive? The vast majority of common tow vehicles like Prados and DC utes are NOT ised to tow heavy loads for long distance at high ambient temps. Why would the manufacturer prioritise the transmission shift protocols for a minority of buyers?
@@SarahandKeelanTravels ...I drive a 2019 Holden Colorado I did add a transmission cooler but basically leave it on drive and keep checking the transmission temp and stays pretty cool (68 to 78 degC) apparently up the hills it changes down with little sense of slippage and down the hills it does a great job at engine breaking, if your on the brake a bit the gearbox drops down a gear and locks, apparently the Colorado has one of the smartest transmission on the market, l just did the Great Alpine Road from Omeo to Bright (around Mt Hotham 1825m altitude, one of the highest roads in Aus) towing a caravan 1700 kgs not a super heavy one but the 6 speed auto puts a smile on your face...I did stop for a while on the way down to cool the caravan brakes but one of the most scenic routes with a great free camp in Omeo and another in Smoko before Bright
So do you want the torque converter locked when towing??
Yes when it’s locked there’s no slipping and less heat, better fuel economy
@@SarahandKeelanTravels so when I go full throttle does it still lock up. I seen somewhere that says almost all torque converters don’t lock up at full throttle
@@SarahandKeelanTravels sorry just really curious is it only good to be locked when your less then 40% throttle
