No scan tool needed, Remove wheel and plastic cover,24mm loosen fill plug, 6mm remove drain plug n drain, 6mm remove plastic drain plug and put back by hand. Replace drain plug lightly. Add new fluid 2 1/2qt tighten fill plug 36ft lbs. put wheel back on lugs 76 ft lbs. use a paperclip connetc to 4 on top and 13 on bottom its 4th one fr right to left on bottom. Start car, put in neutral then neutral/drive 6 times, put in park, leave it running, when D comes on solid Remove drain plug drain until it just starts to trickle, turn car off, remove wire 30ft lbs for drain plug DONE😁😁😁i change out a quart and a half every time i change the oil coz its soooo easy😁😁😁😁
Good suggestion to save money on expensive scan tool. Have you done this many times on the NX200t? No problems afterwards?
@@mackerelvelli yes and its soooo fast n easy👍👍👍
Will that work on a 2006 lexus gs300 as well ? @@lunacallie6858
Thanks! Viktor is a Lexus mechanic and he has the same method without a scan tool and Im not convinced about not using Toyota trans fluid.
Do you have picture of which pins you are using the paperclip on ?
A more affordable scan tool that can read Toyota/Lexus ATF temps is Ancel TD700 (less than $120 on amazon). I've not used it for NX200t yet. It does work on my 07 Tacoma and wife's previouos car, an 07 Lexus ES350. And if the ATF pan is of the typical thin gauge, an IR gun is accurate enough; I've compared the temp variance on these mentioned cars with the scanner, and the IR reading has been within 3 degrees.
You have to be careful with laser temp guns because they can be off quite a bit depending on many factors, but the most important thing here is using a scan tool to put the car in service mode so it brings the engine up to a solid 900 RPM so the proper amount of fluid is circulating in the transmission.
Well explained vedio. You are a professional scince you are using service manuals. Thanks alot. I learned something new in my career
One of the best well explained video...Thank you! If I might add...If you using the good scanner with AT Temperature data stream, you really don't need to put the vehicle into service mode. Once scanner read temp 104, you put fluid till it trickle, then once it read 113, then shut off vehicle, you are done! However, if you don't have any scanner, putting the vehicle into service with the P-D-N-D-N-D...this will do the exact same thing as it indicate correct temp to add, then correct temp to shut off.
The one thing that putting it in service mode does is brings the engine RPM up to 900. That is the speed Toyota wants the engine turning the trans to get the perfect fluid level.
@@737mechanic Got it! Thanks for the explanation...
Thanks excellent vidéo
Another well explained excellent quality job! You do awesome work!!
Thanks buddy. 😊
Great explanation. I have a RWD GS350. I don’t think I can be on the ground filling in the temp window of 103-114F. Thx
What is the mileage interval for the transmission fluid service as shown? Thank you for the details.
I use an infrared thermometer on the transmission pan to measure temperature...much easier.
It can also be much less accurate than the actual temperature depending on the color of the transmission pan, the transmission itself, and the year, make, and model of the car. As far as easier I think connecting a scan tool to a car is as easy as it gets and looking at the real temperature that the computer is actually seeing is as easy as it gets. Plus if you actually want to do it right you need to put the transmission in service mode so the RPM comes up to 900 exactly so the proper amount of fluid is circulating throughout the trans.
I'm confused, once it reaches 104 degrees now your adding cold oil in the transmission? Won't the oil expand now and it be overfill
Back with the Autel I See
Its been about 6 months since I have used it for anything so I figured why not.
@@737mechanic yessir. Always good to have multiple scan tools and interchange them.
@@737mechanic looking to upgrade my current Autel handheld. Which model are you using and how do you find it? Mainly im looking to have the ability to go bi-directional
@@firetechevt I have the Autel MS906TS but the MS906BT is the same one without the Tire Pressure monitor hardware.

But the xtool D8BT is worth looking at because it does more than my autel for half the price.

Thanks for posting up the video. Does the transmission fluid filter not need to be changed?
In most cases, the filter is not dirty enough to need changing. Most of the time what happens is the fluid gets burnt and stops lubricating so the fluid simply needs to be changed and all will be good.
@@737mechanic gotcha. thank you for the info!
Great video!! But realistically...what's the point of changing the transaxle fluid one time with just over 2quarts when all you're doing is mixing it with old fluid that remains inside? Service manual says this needs to be done at least three times to return fluid back to pure/fresh roughly 8quarts later; counting excess pour over.
Yes you are correct and I mentioned that in the video.
@@737mechanic Like I said its awesome to see how in depth you went with this video. But I do have one last question, is there a way to dump all 7.2quarts of old fluid at one time...then just start fresh with new fluid as if it's the initial pour? I also want to stay away from intermixing because it dilutes the new fluid.
@@ryanmolique8137 No, You can get about another 2 or 3 quarts out if you remove the pan but you will never be able to get what is in the converter.
Some clever person could make a fortune by designing some sort of kit, to actually replace the fill plug with a dipstick tube and dipstick. Could probably even make it all electronic, you'd need a temp sensor built into it plus a way to read the level properly... I understand this is another of those Easier said than done" ideas but such add-on parts are sorely needed and you could name your price... NO ONE who cares about their car, believes in "lifetime fluid", it's nothing but a lie!
Do you know if the D8 has the ability to do the same thing as the Autel??
Great procedure just one question. When you open the drain plug at the proper temperature and you get lots fluid coming: I am going to assume that I overfill it when I added the fluid and there was no need to add any extra fluid. I am correct on this assumption.
Yes you are correct.
@@737mechanic thanks
Yes the d8 can also do this
correct me if i'm wrong, using the same method but without using the scan tool u can still get the proper level of fluid pumped in. let say we install the plastic trans dip stick back in, fill the trans with fluid till it starts dripping out = the fluid get to the top level of the dip stick and start to flowing out. put the drain plug back in but not all tied up just loosly.plug the fill plug back tie enough to not get leaking but loosy enough to remove it easily. start the car and let it run for 3 minutes, un plug the drain and fill bolt , pump fluid till it start dripping out, once see the dripping coming to and almost end. tie up the drain and fill bolt. u really don't need to use the scan tool, if u really want to be super accurate, u can measure the fluid that came out and put in the same amount, let the car run for 2,3 minutes, fill till it start dripping then it should get u an even more accurate. i don't think u need to use the scan tool.
You need to at least bring it up to the proper temp.
@@737mechanic u can always use a thermometer to scan the fluid, if it's not yet up to the required temp run it a couple more minutes.my point is we are putting the same amount we were taking out. It has nothing to do with optimal operational temp. It we take out 2 quarts, we put in 2 quarts. Isn't that the goal?
@@antrinh5525 if you are sure the level is correct to start with then you you can do it cold and put back the same amount.
@@737mechanicmy car has 40k on it. Bought it new and want to do this for the 1st time. So its never leaked nothing its in excellent shape. If I drain the pan then standpipe measure out exactly what I drained and put in exactly what drained out maybe add a 2 or 3 oz extra incase of just evaporation or degradation causing it to stay in the filter etc. And just call it a wrap without doing everything else?
@@javiertrujillo3136 Yes that would probably be close enough.
If i dont have the computer to turn on the tc. Is there a diagram on there stating what ports i need to tap in to on the obd2
Yes, email me and I will send you the procedure.
How can I get in touch with you to set up an appointment to do this to my 2014 Toyota Sienna van? I have been wanting to do this for a long time. I live in Waco Texas, so I would like to drive to your place to have you do this procedure to my transmission. Thanks for your help. Rob
you can email me and we can work out a time frame. mechanic737@hotmail.com
I just emailed you now.
Nice job. Have you noticed a change in shifting? Is it smoother or no difference? Thanks
The shifting was already good. I changed the fluid for preventative maintenance. I didn't notice any change but I have seen Toyota transmissions go out just over 100,00 miles because the WS fluid was never changed. The Valvoline maxlife ATF is a better fluid and I want to do about 3 drain and fills to get as much of the fluid changed over to the Maxlife.
Where did you get that service manual?
Pro Demand
$1,200 for autel scanner? NO THANKS😂😂😂😂😂😂
Does the car have to be leveled to do this?
Yes
Good video brother, just one critique. If you are doing a DIY video show people how to do it correctly and safely. Don't show them its ok to NOT use stands. If that car falls its likely going to go sideways, you aren't getting out of the way. If you don't have a second set of stands get some or borrow some, or stack up some wood cribbing. At the very least, slide the front wheels under the car just behind where you are working. At least it wont hit the deck.
You are correct and I should have mentioned that. Personably I never get under a car unless there is a jack stand, but I don't have a problem sticking my arm slightly under the car with it supported by a good jack. A floor jack doesn't have any hoses that can instantly blow out and if a seal goes the jack comes down slowly giving time to pull your arm out. None the less a lot of people have poor quality jacks and they should always use a jack stand.
What if it’s 110 degrees outside already?
As long as the fluid measures that temp you will be good.
@@737mechanic thank you 🙏 it is just so hot outside here where I live. When I start vehicles they almost instantly jump temperature way too fast
WHY? You put in what you took out. Sounds simple enough for me rather than your 'song& dance' But, it is your vehicle. I always put back what I took out and NEVER had an issue with any vehicle.
Because you have NO idea if it was correct, to begin with. So if it was low it will still be low and if it was overfilled it will still be overfilled. This is simply showing how to do it correct for people who want to do it correct.
These guys don’t know what they’re doing, why do they measure trans temp for ? Yes i put in the amount i took out. No need bs,
@ So lets say the trans was low or even over full and you put that same amount back in that means it is still low or over full. Does that make sense? The ONLY way to make sure it is exactly at the correct level is to measure the temp and in the case of Toyato and Lexus put it in trans service mode so the engine runs at exactly 900 RPM so.
BTW the only people that don't know what they are doing is people that put in the some amount they drained out and think they are doing it right.
Toyota designed the transmission so their service procedures are the way it should be done.
@@737mechanic This procedure only applied when you replace or service Brand New Fresh Transmission, let's say they will do this in the Lexus Factory before the vehicle passed all inspections and ship to the customer.
I'm not saying you're doing it wrong I'm saying you're wasting time and end up you get like 1.5 liters out of the NX Trans right ?, the Rav4 2.5L engine you'll get like 2.5L Trans fluid out, the Lexus 3.5L engine you'll get like 3.5 liters out.
You do trans fluid when it's cold, so if you drive to your mechanic shop let's say 3-4 miles away, wait like 2 hours until your trans cooldown, and then you drain your trans fluid out, measure how much out you put back exactly amount in, little more is fine. ( the reason why Trans has overflow).
and then you turn on your engine Shift from P to D each one like 6 secs and you'll be good to go.
and for those who doing Trans Flush also use your procedure, the Trans system holds about 9 liters (10 US-quarts) if you flush everything out, the same as when you replace the whole brand new transmission.
Now you know right ? peace out bro !
@ There is no overflow, there is a vent tube and, in some cases, if a transmission is overworked fluid can cavitate and it will blow out the vent tube which will end up causing fluid loss not to mention if there ends up being a leak that goes unnoticed. The reason Toyota came up with the procedure they did was because people could not get it right even when there was a dipstick so now there are people that think as long as you put the same amount back in you are good but that is NOT the case.
Why not measure the fluid that comes out and replace with the exact amount? Seems like a much simpler way of doing it.
You can do that but you are guessing that the fluid level is correct when you start, if for some reason the fluid level is low or even high and you put back in what came out then you are still low or high. If you do it the way Toyota says you will be at the proper level 100 percent.
With that said I did a video doing this a second time by draining and measuring and refilling with the same amount but I only felt confident doing that because I had done the refill the proper way so I knew in a month the level would not have changed.
Your vehicle doesn’t look level to me.
It was level.
