Great news to hear... glad you're sticking around. Faith is good 👍... great video and good information 👍 As always looking forward to seeing what's next. 😎
Trans cooler upgrade is completely worth the peace of mind. On some of the older trucks, lb7, lly, lbz at least, it's well worth it to swap out your OEM transmission lines at the same time for more robust aftermarket lines. Get the confidence one of those tired old hose crimps doesn't let go, better serviceability, and any sludge that's built up in either is removed from the equation.
Very worth it, my 2012 6.7l Cummins, I dropped 15 degrees with a mishimoto tranny cooler. Pulling a bumper pull 9.5K trailer I was @ 194 in a 102 degrees. Now Im @ 180 pulling the same trailer. peace of mind is great.
Aftermarket trans cooler was a solid upgrade for my lb7. Dropped trans Temps by 20 degrees and engine Temps by 10 degrees. The mountains I'd overland on that would overheat my engine were no problem after that!
@beowulf885 Hey man, no problem. I used a different trans cooler, but they should work the same. The trans fluid routes through the radiator to both cool the trans fluid when it's hot and to warm the trans fluid when it's cold. The hot trans fluid heats the radiator, which in turn heats the coolant and heats the engine, or otherwise exceeds the ability to of the radiator to keep temps within optimal temps. Also, the trans is bolted to the engine block, so the hotter the trans the hotter the engine and visa versa. So cooler trans equals cooler engine. I explain it on my channel if you want to come take a look sometime. Next, I'm installing an aluminum radiator to see how that affects the overall cooling. I'm especially interested in how much the clutch fan engages after that.
I have a 2019 Denali L5P, i installed the WC FAB bypass thermostat and while hauling my 15,500lb 5th wheel i've seen trans temps as hot as 140 degrees, on a 12hr trip,on the stock trans oil cooler.
I put the mishimoto trans cooler in my lbz. Dropped the trans temps a good 30 degrees over the factory trans cooler. I was getting 105-115 over ambient towing the passes with my travel trailer. Now I am lucky if I get 90 over ambient towing and typically run around 70-75 over ambient not towing instead of 90-100 over. At the same time I did a coolant flush, cleaned my stack, and installed the upgraded kennedy fan clutch and it also helped keep my engine running cooler as well. The fan clutch kicks on at 198-200 degrees instead of 220-225 like the original would so my engine runs much cooler as well. The best upgrades I have done to any my trucks is upgrading cooling on both the engine and transmission.
100% agree with the aftermarket trans cooler. I installed one on my 2002 LB7 and it made a night and day difference. Haven’t pulled my 32 foot camp trailer with it yet but will coming up here in a couple of weeks for the deer hunt. Can’t wait to see the temps I get now.
@@p.b.sHUNTING yes, the trans cooler is from PPE. It’s about twice the size of the stock trans cooler and so far has been working great. I didn’t know about the one you mentioned. I would have looked at that one as an option as well.
@@davidtmcgowan440 it may have more depth, but that’s not what cools the fluid…. Length of fins is what allows cooling time, and the PPE is literally the same size as the stock unit.
I am so glad your channel got re-monetized. You very much deserve it. I know you work hard to get these videos out to all of us. And there is solid value in your content. So there is every reason to get compensation for your hard work. I just wish Google would put the "Don't" back in their mission statement. God bless you and your family sir.
That trans is known for The Transmission Thermostat to stick. You can install a bypass valve. I would only do it if towing a lot. Just did a 2018 and temps down to 174 degrees with 15K on.. Great Video! Love em !
I’ve had the double stack trans cooler with the fan setup. I’ve hauled heavy loads over mountains in the west and in the south with my 06 lbz i never saw temps over 175-180. Big time worth it
It almost sounds as though there was a single person at UA-cam fucking with you Josh and they finally got caught. Lets hope so. Great video. People don't realize how beneficial an after market cooler is. Hot trans fluid is the number one killer of transmissions. I've never seen temps on my Allison above 180 degrees after installing mine and that's pulling 12k on a 100 degree plus day. They simply work!
On my LMM, i installed the PPE transmission pan and so far only 190F with moderate weight in Virginia. The pan does reduce the ground clearance, but the logging roads i might drive in are usually graded enough for a Peterbilt to come out. For the 15 degree drop in temperature, that cooler is well worth it
Btw congrats on getting the UA-cam thing figured out. If u see this, from my understanding there is a way to submit ur video to UA-cam before it even gets released, to make sure all is good. DDE made a post to whistlin diesel about do that since they were having problem with that as well. Life of Palos was the 1 that mentioned it in a recent video. (Has a pic of cleetus & his wife as the preview of video)
I did a direct fit aftermarket trans cooler on my lmm. I did notice around a 10 degree difference even in stop and go traffic. I also installed a trans go shift kit. Worth the money.
Josh that brings a idea why not make and sell bumper extensions so the front bumper sits 3 to 4 inches forward it would provide a step to get under the hood easier
Added the mitsimoto trans cooler on my 03LB7 along with a deep sump trans pan. Temps decreased apx 20 degrees cooler pulling heavy. Takes a bit longer to raise and lower temps. With deeper pan. Great investment!
Don’t forget there’s a thermostatic valve inline with the cooler lines on these trucks. A cooler won’t do much until that valve is bypassed because it’s like a thermostat in an engine it wants the truck to heat up to a certain temp before allowed fluid through to the cooler
Does PPE make an upgraded bypass for your GMC? If they do, you might want to try it. I installed one on my Silverado, and it definitely was worth the 90 bucks.
06 lbz 6 sp. with 5/8 cooler lines and upgraded trans cooler, when I was pulling a big grain cart I could only go about 50 mph or engine would get towards hot. I locked it in 4th and trans keeps heating up over 235, but if I let it go to 5th it didn't heat the trans as soon. I just added PPE trans pan too see if that helps.
PPE doesn’t claim to lower your trans temps as contrary to belief, the main claim is that the transmission temperature’s are going to be staying lower and colder over a longer period compared to the factory cooler because of higher capacity and bigger cooling area
This is the video I’ve been waiting and that’s awesome news that everything got fixed on the channel. Very happy to hear that. I’m definitely getting mine. Installed pretty soon for my L5 P.
Hey TM i have and Xtrude 30,000 GVW transmission cooler with fan it maybe overkill😁 but anyway I had to make brackets so i could fit it behind the GMC emblem but I can tell you it makes a huge difference with my transmission temperature, tranny never get's over 195* on the hottest days towing down the highway
"This thing has a 36 gallon fuel tank"... Well I'm jealous. My truck used to have a 34 gallon tank. I say used to, because I bought a cheap, made in China fuel cap, and the vent didn't work. I drove for a couple of hours, stopped to refuel, and I didn't have the arm strength to remove the fuel cap. The vacuum was so strong, I had to pry the cap off. The vacuum caused the tank to start collapsing in on itself. Now my 34 gallon tank is about 26 gallons. I've since added a 88 gallon aux tank + tool box in the back, so not so bad. Just got a better quality cap for my aux.
The later LML and the L5P uses a thermostat to control temperature on the transmission. So the cooler will only help when the heat load exceeds the stock cooler.
Just pull the thermostat out of the cooler line and it will run much cooler. No need for another one on the L5P. Mine runs 150 degrees pulling a trailer in the middle of the summer heat.
Back when I was still truckin with the Zebra, I had a couple small but very powerful fans on a manual switch I could turn on for climbing mountains and to cool the trans faster on the way down. Also used it a lot during the summer running hard then getting into slow traffic. That trans was holding 2,500 pounds of torque and those fans always kept it under 200 degrees which was really impressive running in the southwest mountain ranges in the dry summer heat. I think the same concept/idea could be applied to just about any truck.
I bought a ppe trans cooler for my 330k mile lly because I tow a triple axle gooseneck trailer with trucks on the back and it never goes over 180 and before it would be over 220 when towing
You should probably install the Wehrli Custom transmission thermostat bypass plug too. Synthetic trans fluids are not dependent on a specific temperature range to properly have the additive packages in them to perform properly compared to older mineral based trans fluids. The factory plugs have stuck closed. Great insurance policy.
That LBZ sounds wicked...buuuut that L5P though..... since the DPF was "cleaned out" it really sounds good! If I were a rich dude, I would sponsor an install video of a 64mm 9 blade, along with some Kryptonite front end goodies on that '18. But since I'm not rich, I digress. Still working towards my first diesel 🤷♂️ God Bless- Old Sarge from near Pensacola, FL.
Good video Josh ! Btw I fly from France to Chicago last week and I stopped at Ryan’s diesel service on my way to Iowa. I spoken to him for a couple of minutes. Such a cool guy 👍🏻
I added a trans cooler to my 2001 GMC Sierra 5.3L after finding my trans oil was black. Since the 1/2 ton didn't have a trans temp gauge, I added one as well. After flushing and replacing with synthetic trans oil, the temp only got to a high of 204° when pulling an 8k Travel trailer up over passes at 11,000 feet in the Colorado Rockies. This had that 5.3L in 1st gear working hard and needing air. On the highway towing it now stays a cool 165°. Going to get a Duramax someday but in the meantime, that trans cooler is great! I should add that after a season where the engine got hot towing, I replaced the thermostat, water pump, and fan clutch. Engine never overheated again. That fan clutch can slip and then nothing gets cooled properly.
Ive been wanting to put a aftermarket trans cooler on my 08 max but till now havent found a good one. My stays around 215-220 and this looks like would help with that for sure . Thanks
Doesnt work on 2011+ Powerstrokes as the temp regulator is in the solenoid body which is set to 190F. SPE sells a new solenoid body set to 160F I believe.
Thanks for the video. My trans cooler caught a stone and has a small leak now so I’m in the market for an upgrade now. On another note what kind of rims are those? I might need to get some
I bought the PPE trans cooler for my LBZ because a deer hit crunched my OEM. I never really tow, and see the trans Temps 15 to 20 degree cooler cruising. I also did Deviant hydraulic transmission lines for maintenance.
What do you think of this?I'm thinking about installing an even bigger cooler,but above the rear axle between the frame rails.Yes,it'll have an electric fan pulling air thru it too since air flow won't naturally flow as much as factory location.The reason I'm hoping to mount it there is to reduce under hood congestion and find/fix potential leaks in future.Considering a pull off from a Kodiak type truck.Big,but still duramax/allison combo. Thanks for help. Thanks for your service and God continue to bless.
My LML Duramax ran around 140 pulling a cat skid steer 2 hours from home did very well it was during November Thanksgiving break. So it wasn't normal Texas Temps
tebgi a question regarding a 2004 lly that comes with a gdp tunner but it is not connected to the obd2 it helps me to verify codes but if I put an edge cts3 on it to look at the gauge information it will work as well it already has the 5 position switch
I am replacing my blown cooler with this same one, 2015 3500, here in a few minutes it will be installed. I do haul a 17k tri axle camper, so I am looking forward to heat reduction.
Seeing that you installed a little bit larger transmission cooler being up north, do you not run a cover over the front of your truck? It keeps all that harsh cold air from hitting the front.
On my 3.0 duramax, I used a PPE trans bypass and cooler. dropped my trans temp from 198 to 122 ish not towing. I think 140 is towing my boat. Real test in a few weeks
When you did your tests - did you account for the outside air temp (OAT) on each test? That's really what will help you measure your transmission cooler efficiency. The delta between your OAT and trans temp is what you want to measure. I installed a larger cooler on my 09 Tahoe and dropped the delta to about 50 degrees from OAT at highway speeds, or 80 degrees delta from OAT while towing. So, if it's 100 degrees OAT out, the highest I see on straight and level while towing is 180. I also have a 24 Silverado 2500HD - I'm thinking about the PPE trans cooler for that. But don't know if I will see that much of an improvement.
Hey, what's the best tuner I should get for my 05 lly duramax? I have a s&b intake and plate deleted 4inch exhaust pipe. I plan on doing some regional hotshoting with it
Is there a reason why not to run trans lines straight to the cooler and back to the trans ? Do hook it up to the radiator. Using a ppe cooler seems it would run cooler that way
Hey Josh I pull for a living I drive a 23 model L5P and I run around 167-172 degrees loaded heavy! The highest i have ever seen was pulling a huge mountain loaded very heavy and I was barely over 200 degrees and cooled off as soon as I got rolling hood.I would look into wy your trans is runnning so Hot!
What was the weather 90s or above? I'm sure you hauling around to various states with the air on and the hills with a 100 degree and a feel of 110. Whats the reading please? I have a 3500HD chevy duramax 2024 dually RV transporter 90k miles and in sizling temps the trans is bailing out. So any thoughts would be greatly appreciated thanks
Hello, very good video! I have a question! Do you think this works for a 2009 Peterbilt 335 automatic transmission, px6 engine? It is a tow truck and I feel like it needs another cooling system.
I've seen videos of guys flipping these coolers upside down on the bracket so it's placed higher up so theres less restriction from the bumper and more air through the grille, would you recommend this?
Thick master., this comment is kind of off topic. I tried to find a spot to make this comment but this is the only way I can get it to you. I have a 2005 2500hd with the LLY and I’m sure you know about the LLY overheating when towing heavy loads. I guess they upped the performance from the 2001-2004 models but didn’t increase the cooling capacity on the lly. They did fix the problem in 2006 and up by increasing the cooling capacity. I researched the crap out of this issue and finally came to the conclusion that the only way guys have fixed this issue is by adding an auxiliary radiator. I am about to do the project myself but figured I would give you the opportunity to do a video on this subject even though I believe you don’t have an lly. I think it would help a ton of people out as the mod is hidden in the diesel forums but is the only proven fix with the 2005 lly. Thanks man. I watch all of your videos
This l5p sounds good brother did you is it 5 inch straight pipe? Or what’s the exaust set up I want to delete mine and I’m deciding either do 5 inch or use the def cat and stock exaust…
I went the Mishimoto transmission cooler route and 5/8 transmission lines. It mounted below my factory cooler. So thinking I could link the two together, also installed the PPE transmission pan averaging 160 degrees normal driving temperature. My cooler sets in front of my radiator with a gap of about 2 inches on my LMM.
Do those 2500 trucks have the thermostat at the trans like the 1500 trucks do? If so get the bypass from ppe for that too and it'll really lower the temps... Great video man and glad to see you're back getting money from this.
I drive hotshot all over country had a ppe cooler on my 21 duramax it lowered temperature a lot before I installed it transmission temp was always over 230 pulling heavy load’s threw mountains now have a 24 duramax need to get one for it
I've got a 2019 GMC 3500HD my trans temps with a stock cooler pulling our 17k fifth wheel are typically 174 -185. Not sure its even gotten over 200 even pulling the mountains of Colorado. So in that case I don't see any benefit for me to upgrade the trans cooler.
Great news to hear... glad you're sticking around. Faith is good 👍... great video and good information 👍 As always looking forward to seeing what's next. 😎

Keep in mind that stock one had quite a bit of fin damage. But either way it'll keep temps lower which is good.

I bought the PPE trans cooler for my LBZ because a deer hit crunched my OEM. I never really tow, and see the trans Temps 15 to 20 degree cooler cruising. I also did Deviant hydraulic transmission lines for maintenance.
What do you think of this?I'm thinking about installing an even bigger cooler,but above the rear axle between the frame rails.Yes,it'll have an electric fan pulling air thru it too since air flow won't naturally flow as much as factory location.The reason I'm hoping to mount it there is to reduce under hood congestion and find/fix potential leaks in future.Considering a pull off from a Kodiak type truck.Big,but still duramax/allison combo.
Thanks for help.
Thanks for your service and God continue to bless.
My LML Duramax ran around 140 pulling a cat skid steer 2 hours from home did very well it was during November Thanksgiving break. So it wasn't normal Texas Temps
tebgi a question regarding a 2004 lly that comes with a gdp tunner but it is not connected to the obd2 it helps me to verify codes but if I put an edge cts3 on it to look at the gauge information it will work as well it already has the 5 position switch
How about run the transmission lines straight to the cooler and back to the transmission . Not going into the radiator see what the temp is
I am replacing my blown cooler with this same one, 2015 3500, here in a few minutes it will be installed. I do haul a 17k tri axle camper, so I am looking forward to heat reduction.
what kind of lift do you have on the LBZ and do you recommend it?
Seeing that you installed a little bit larger transmission cooler being up north, do you not run a cover over the front of your truck? It keeps all that harsh cold air from hitting the front.
On my 3.0 duramax, I used a PPE trans bypass and cooler. dropped my trans temp from 198 to 122 ish not towing. I think 140 is towing my boat. Real test in a few weeks
can you do a double trans cooler? add it in series instead of replacing the factory one?
I'm so happy to see you back on. Was kinda of worried.
When you did your tests - did you account for the outside air temp (OAT) on each test? That's really what will help you measure your transmission cooler efficiency. The delta between your OAT and trans temp is what you want to measure. I installed a larger cooler on my 09 Tahoe and dropped the delta to about 50 degrees from OAT at highway speeds, or 80 degrees delta from OAT while towing. So, if it's 100 degrees OAT out, the highest I see on straight and level while towing is 180.
I also have a 24 Silverado 2500HD - I'm thinking about the PPE trans cooler for that. But don't know if I will see that much of an improvement.
I’m glad to see your channel is back on track, excellent video Josh 👍😁
Mine started to leak sunday... PPE got delivered today for $50 over oem from the dealership I figured why not upgrade....
Even the upgraded trans coolers make a big difference on the gassers same as it does on the diesels.
Yep I did it on my bro n laws truck.
Also, don't answer that scammer that replied to u
(Report if u will)
I get around 30° difference on a hot day in the Ozark Hills: 30 foot camper loaded. 2002 LB seven built tranny.
Hey, what's the best tuner I should get for my 05 lly duramax? I have a s&b intake and plate deleted 4inch exhaust pipe. I plan on doing some regional hotshoting with it
Is there a reason why not to run trans lines straight to the cooler and back to the trans ? Do hook it up to the radiator. Using a ppe cooler seems it would run cooler that way
Doesn’t the stock l5p have a trans cooler thermostat?
Man i need that cooler for my Cummins because when i haul anything heavy it goes over 200 everytime!
Hey Josh I pull for a living I drive a 23 model L5P and I run around 167-172 degrees loaded heavy! The highest i have ever seen was pulling a huge mountain loaded very heavy and I was barely over 200 degrees and cooled off as soon as I got rolling hood.I would look into wy your trans is runnning so Hot!
What was the weather 90s or above? I'm sure you hauling around to various states with the air on and the hills with a 100 degree and a feel of 110. Whats the reading please? I have a 3500HD chevy duramax 2024 dually RV transporter 90k miles and in sizling temps the trans is bailing out. So any thoughts would be greatly appreciated thanks
Very nice truck! : ) What size wheels and tires are those? Thanks in advance for the info.
Thanks 22/12.50R22 -24 offset
Hello, very good video! I have a question! Do you think this works for a 2009 Peterbilt 335 automatic transmission, px6 engine? It is a tow truck and I feel like it needs another cooling system.
do they offer aftermarket lower thermostats? If you got the coolant temp down, wouldn't the transmission temp get lower also?
I've seen videos of guys flipping these coolers upside down on the bracket so it's placed higher up so theres less restriction from the bumper and more air through the grille, would you recommend this?
Thick master., this comment is kind of off topic. I tried to find a spot to make this comment but this is the only way I can get it to you. I have a 2005 2500hd with the LLY and I’m sure you know about the LLY overheating when towing heavy loads. I guess they upped the performance from the 2001-2004 models but didn’t increase the cooling capacity on the lly. They did fix the problem in 2006 and up by increasing the cooling capacity. I researched the crap out of this issue and finally came to the conclusion that the only way guys have fixed this issue is by adding an auxiliary radiator. I am about to do the project myself but figured I would give you the opportunity to do a video on this subject even though I believe you don’t have an lly. I think it would help a ton of people out as the mod is hidden in the diesel forums but is the only proven fix with the 2005 lly. Thanks man. I watch all of your videos
That was a typo… it was supposed to say truck master…lol
Where is the best place to get a PPE lower radiator hose for a 2008LMM Duramax? Or do you sell them?
Do these newer Duramax trucks naturally run warmer. My LBZ tranny has never seen over 200 deg and that’s gross combined 25k in Arizona heat.
Do the HD's have trans cooler thermostats like the 1500's? Would a thermostat mod/upgrade make even more of a difference?
That stock L5p sounds pretty good ;)
The biggest help on my truck was cleaning the radiator. Mine was half plugged with cattail fuzz and bugs
@Truck Master are you still running the Pulsar V3? What is your thoughts and gains any in mileage or just fun at the skinny pedal?\
I have 1 minor delima with temp readings .. what was differences in outdoor Temps... I'm Michigan as well and we know how it swings
Hey glad everything worked out for you! Also my cp4 pump went out and 12k to fix everything…. Definitely need to do the swap
i got my temp down to 160 with a heavy load in Arizona in the summer
This l5p sounds good brother did you is it 5 inch straight pipe? Or what’s the exaust set up I want to delete mine and I’m deciding either do 5 inch or use the def cat and stock exaust…
I went the Mishimoto transmission cooler route and 5/8 transmission lines. It mounted below my factory cooler. So thinking I could link the two together, also installed the PPE transmission pan averaging 160 degrees normal driving temperature. My cooler sets in front of my radiator with a gap of about 2 inches on my LMM.
Just wondering if you should remove the trans oil thermostat (bypass valve). If the temps drop significantly, then maybe bypass valve needs upgrading.
Do those 2500 trucks have the thermostat at the trans like the 1500 trucks do? If so get the bypass from ppe for that too and it'll really lower the temps... Great video man and glad to see you're back getting money from this.
Don't answer truckmaster904
It's a scammer
I drive hotshot all over country had a ppe cooler on my 21 duramax it lowered temperature a lot before I installed it transmission temp was always over 230 pulling heavy load’s threw mountains now have a 24 duramax need to get one for it
what did i win scam
I live in FL I have a l5p trans bypass plug from wheril haven’t seen above 200* towing drive around 150* $50.00
is that the 9 blade turbo from rds on the red dmax? sounds crazy
All you really need to do is install the WC fab transmission thermostat cooler bypass and it works like a charm.
I've got a 2019 GMC 3500HD my trans temps with a stock cooler pulling our 17k fifth wheel are typically 174 -185. Not sure its even gotten over 200 even pulling the mountains of Colorado. So in that case I don't see any benefit for me to upgrade the trans cooler.
I'm glad they have fixed your stuff bud
Does your l5p have that ticking noise while idling ?
Did you ever do the bypass block or plug on your L5P? Before the trans cooler? Just a curiosity. Much love
Take out the in line thermostat and the temp will drop even more. I did it on my 2017 3500 L5P.
