    Uninstall the thermostat and reinstall the adapter plate, disconnect the cooler rubber lines off the hard lines. Remove the hard lines from under the truck. Remove the grill and unbolt the trans cooler and remove with the rubber lines. Reinstall the grill and your done. ATF level should be very close to same level because your not adding any components.

    Ok so everything then, my thoughts exactly on removal but pretty sure it would take me a good while longer.

    It would be quicker than you think. You know where everything is from the install and you won't have to play with the aft level. I think the hardest part would be removing the grill for most. I didn't even remove my skid pan for the install.

    Well, I did, but I noticed that there's no section anymore for just buying the plumbing as one big bundle. I mean it's easy to copy the part numbers into sparks parts and get it all for the same price or slightly cheaper using tundras.com discount code if anyone is wondering. Just wasn't sure if there was a specific reason he doesn't have the plumbing package available anymore.

    You might want to reach out to him personally on here. I bought mine a few months back and he had the full kits. It's probably just part availability.

    I bought the full kit not long ago. I have been waiting to install it until my color matched grille showed up. Well it finally showed up on Saturday so it's time for a Grille, tranny cooler, front camera, and skid plates.

    Nice! I installed mine last weekend, not that hard, which is great...still haven't given it a thorough test though. I actually found the catalytic converter plates much harder/more frustrating to install than the cooler. Lol

    I think this is a great plan of action and very helpful information. It assumes the failure will occur at a time and location where you’ll have the ability to remove the necessary parts. My luck it will happen in August on I-10 in the middle of the ARIZONA desert when I have a Swiss Army knife.

    Personally I would just bring it in. Very unlikely anyone at the dealership would care unless you did something wrong with the install.

    Ran through the 7 pages of data, don't have the ATF degradation value. The page that has AT info is missing it :(

    @e30cabrio That’s disappointing for sure. You might want to dive into the TIS and look for your specific year ATF change procedure. If it has the step to reset your thermal degradation estimate, it probably means that you need a different version of Techstream to get to it.
    @Ruggybuggy What would you recommend in this case?

    Do a YouTube search for fluid replacement. There was a guy on there that pulled one of his rubber lines off to drain out most of the ATF. Draining just the pan only gets maybe a 3rd of the fluid.

    Thanks, I'm aware I plan on doing it 3 times over a few months.

    I did a full flush on my Tundra & ended up replacing my transmission. Don't want to spend another 2k on a trans r&r.

    I think everyone who doesn’t reset the thermal degradation estimate after replacing ATF is risking an accelerated wear of the clutch packs. The trans is still thinking that your ATF is old and shearing and applies max pressure at each shift, causing too much wear in a very short amount of time.

    I guess that's why paying a dealer is cheaper. I did not know about that.

    I need to find out how to reset it before I do anything.

    edit

    Is this right?
    http://www.ttundra.com/1051/initialization.html

    INITIALIZATION

    1. RESET MEMORY

    NOTICE:

    • Perform Reset Memory (AT initialization) when replacing the automatic transmission assembly, valve body assembly or any of the shift solenoid valves.
    • Reset Memory can be performed only with the Techstream.
    HINT:

    The ECM memorizes the control conditions of the automatic transmission assembly and engine assembly. Therefore, when the automatic transmission assembly, valve body assembly or any of the shift solenoid valves has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.

    The reset procedure is as follows.

    (a) Connect the Techstream to the DLC3.

    (b) Turn the ignition switch to ON.

    (c) Turn the Techstream on.

    (d) Enter the following menus: Powertrain / Engine and ECT / Utility / Reset Memory.

    NOTICE:

    After performing Reset Memory, be sure to perform the Road Test (See page [​IMG] ) described earlier.

    HINT:

    The ECM learns through the Road Test.

    2. ATF THERMAL DEGRADATION ESTIMATE RESET

    NOTICE:

    If either of the following conditions is met, perform ATF Thermal Degradation Estimate Reset.

    • The ATF has been replaced.
      HINT:

      If 50000 or more is displayed for the Data List item "ATF Thermal Degradation Estimate", thermal degradation of the ATF is suspected. Perform ATF Thermal Degradation Estimate Reset after replacing the ATF.

    • Approximately 50% or more of the ATF has been replaced during a repair of the transmission or a similar operation.
    (a) Connect the Techstream to the DLC3.

    (b) Turn the ignition switch to ON.

    NOTICE:

    Do not start the engine.

    (c) Turn the Techstream on.

    (d) Enter the following menus: Powertrain / Engine and ECT / Utility / ATF Thermal Degradation Estimate Reset.

    If you know the service history or have the truck since new, you can do partial replacements (drain and fills) every 30k miles or so. That way the fluid is always not too fresh and not too old - hence no issues with clutch packs. Otherwise there's plenty of horror stories like 'Valvoline MaxLife (Amsoil, etc.) killed my transmission after full replacement'.

    Yes, this looks exactly like the instructions for my 2021.

    It was also suggested I try resetting in the utility section. That is there but fails:

    Have you actually confirmed that the ATF Thermal Degradation Estimate value has an actual effect on the SLT solenoid/line pressure?

    In the "modified valve body" world, the main goal seems to be boosting line pressure/speeding up shifts to prevent unnecessary slippage. I fail to see how "max pressure at each shift" is causing too much wear to the clutch packs -- I would expect that if anything, the max pressure would cause high shift shock, but not necessarily shorten the life of the clutch packs.

    I don’t know enough about modifying the automatic transmissions but always thought that boosting the line pressure and quick shifts are accompanied with aftermarket clutch packs that can withstand that abuse.
    I would feel safer resetting that value after there’s new ATF in the trans or any mixture of the old and new ATF. Just let the trans figure out how much pressure it needs to properly shift under new conditions.

    Aftermarket clutch packs are certainly an additional enhancement that can be made to the AB60 series transmissions in these trucks (looking at IPT/Level 10 as package options that have already selected the plates for you), but the stock clutch packs themselves seem to be holding up pretty darn well to modified valve bodies in the supercharged world.

    I agree that one should follow the ATF degradation reset procedure after doing a drain/fill, but I was curious about the claim that the degradation value was directly affecting SLT/line pressure. I suppose it would make sense, but I would actually expect the transmission adaptation logic (that can be reset through "Reset Memory" for AT Initialization) to handle choosing how much line pressure to apply. Otherwise, I wonder if the figure is just a superficial number used during diagnosis to determine whether to replace fluid or not.

    Sure, there’s no portable chemical lab inside of that transmission to run the analysis, hence the ‘estimate’. Maybe I will be able to dig out some Aisin documentation that talks about how that parameter is calculated.

    If there is AW documentation that points to the ATF Thermal Degradation value having an effect on line pressure, that would certainly put an end to my curiosity there. I've seen the same type of info floating around on the Volvo forums (that use Aisin transmissions as well)

    What's interesting is there are stories out there of folks that have seen their ATF Degradation number go from 0 -> 65535 in a span of 10k miles without changing the fluid, which leads me to believe that the ECM is setting that figure using more data than just temperature. I wonder, if the ATF Thermal Degradation number affects line pressure, if the transmission might actually "roll the number back" slowly if you replace the fluid without resetting the number.

    So if we do a simple drain and fill at the recommended mileage are you supposed to do this atf reset procedure? There are several threads on atf drain and fills on this forum and this is the first I've ever heard of such a thing.

    @Oats87
    I found some good info on Russian Toyota/Lexus forums, but that’s obviously not coming directly from Aisin. What I’ve learned so far:
    - aging ATF has increased viscosity
    - transmission has to adapt to it by increasing shift times (no info about the line pressures)
    - new ATF with low viscosity plus increased shift times will lead to slipping and harsh shifts
    - the transmission computer will eventually relearn and will start shifting smooth after some time
    - adaptation reset helps to decrease the relearn time and avoid unnecessary wear related to harsh shifts
    - AB60 series is very forgiving in terms of what’s in it unlike the FWD Aisin transmissions

    I will keep a log of how my ATF degradation estimate changes over time. Just drove at 80 mph today for a few hours with 1100 lbs of payload and never saw the pan temperature above 200 F. At 70 mph it is more like 195.

    1 drain and fill is less than 50% of new fluid. No reset is required per Toyota’s repair manual. Two sequential drain and fills is something like 55% of new ATF and then you will be better off with the reset.

    Looking at getting the transmission cooler kit for a 2020. Noticing the coolers are a little different.

    I am seeing the Hayden with the inlet and exit on top. The billet one (MHX-514) with side inlet and exits, and the Setrab one that is narrow and turned sideways.

    Is there a consensus on which one is best?
