    Kits doing great. Pulled the pin on the thermostat this morning and went on a nice spirited drive followed by a long stint at 75 on the hwy, pan temps never pushed passed 190 and the TC only got over 200 momentarily. This cooler is definitely more efficient than the one I had on my 16 as that truck would still cruise around with the pan in the 200s.

    Just paid for a kit. Lots of money but after reading all pages in this posting, it seems to make sense long term!

    I got the Toyota parts, and a couple feet of 3/4 by 1/8 aluminum stock. Bent the stock into brackets and mounted the cooler. Then brought the truck to the shop and had them do the rest.

    My temperatures are great but I have noticed it now does not shift the same as before. It wants to be in a lower gear, so as you accelerate it holds the gear longer and when slowing down it down shifts to early. And no, I do not have the tow/haul button pushed.

    Anyone else experience shifting issues after mounting the cooler?

    The cooler is a 'Derale 13504 Series 8000' and the hoses they used between the hard lines and the cooler say "Gates Plant Master XTreme 325" on them. Rest of the parts are Toyota parts.

    They said they added about a Quart of trans fluid.

    What are your temps? They may have left the thermostat pinned open causing your ATF to never reach operating temperatures.

    Only other thing it could be is they did not do the ATF level check properly however, it should only need between 1-1.5 quarts of ATF when adding a cooler.

    They removed the pin (gave it back to me along with the spacer).
    pan temp goes up to 180-185, tq temps go 180 to 195 during normal driving.

    I will bring it back and have them check the fluid level.

    Ditto this.

    My install took almost EXACTLY 1 quart of ATF to be at the perfect fluid level.

    Truck drives and shifts perfectly and no different than before the cooler install.

    If you have ANY mechanical ability at all... (or even just common sense)... you can handle the install.

    There is nothing "rocket science" about it.
    A few bolts, a few hoses and clamps, a quart of ATF and grill R&R is about all there is to it.

    90% stock , Daily Driver / Tow Vehicle , Retrofitted Trans Cooler , 10 Ply tires

    Id be concerned about the choice of hose used in your installation of the cooler ,,,, If you look up that specific hose it comes up as an "air / water" hose , it does not state that it has any resistance to petroleum based oils , or that it is suitable for any automotive use . Also its operating range is -40 to 212 degress , the atf running through those hoses is going to be knocking on to max operating temp .
    If I were you I would switch to a specific transmission oil cooler hose made for the application .

    That’s why Toyota will never say you can add your own cooler and they will fully warranty it. Too many variables and some not doing it right.

    So just add a quart of transmission oil and don't be concerned with the transmission temps when filling?

    I would (and I did) follow the factory procedure for checking fluid level... since there is no guarantee that the level was correct to begin with... and... cooler capacity will vary... but adding a quart should be pretty darn good starting point... since you have to account for filling both the cooler and 10ft of 3/8 line/hose.

    In my opinion... still quite simple to get to checking temperature and remove 2 plugs to add/drain/level fluid. :thumbsup:

    Thanks, I will get new hoses. On Amazon found 'Derale 13016 Transmission/Engine Oil Hose' and ordered it.

    After driving it a few days shifting has returned to normal.

    I've seen several members stating that their dealer said they would install the cooler, however, I don't recall anyone coming back and confirming they did so.

    It would be nice if you (or anynody else that had this installation done by their dealer) could chime in and tell us about it after the fact.

    The dealer shouldn't have any issue installing the cooler. Its work and they will gladly oblige. It will be interesting what they will charge because it's something they would have never done before. I'm guessing the price will vary quite a bit.

    $300. I could probably do it myself, but I know who to call if something goes wrong.

    Seems like Toyota would have a hard time denying a warranty claim if their dealer installed the cooler.

    Agree, and that could set a good precedent, that´s why I posted this:
    Let's wait and see if someone chimes in.

    Not at all. Dealerships can act independently, and a dealership doing the work doesn't force Toyota's hand on the warranty issue.

    My own Derale Cooler 13614 installed today, purchase some angle aluminum from Lowe's, installed vibration isolators at each point. Got a $10 fluid pump from Napa. Pumped in half a quart of Amsoil OE transmission fluid. Used my torque app to check the transmission pan fluid temperature. Also verified it with the jumper wire at the DLC connector. Removed the check plug/bolt. After verifying there were no leaks I did a 30 minute drive. Watched the transmission temperatures dramatically less than what they were before. After I was confident all the air was out of the system. I removed the pin from the transmission thermostat. Drove the vehicle another 30 minutes back home and watched the fluid temperatures stay between 177 + 182 degrees

    I am a happy camper now
