Did you read the report? It's all below what would be expected for a similar transmission with 38K miles.... I'm starting to read Toyota branded WS good to 300° and I'm positive I had it well over the 260° I monitored. That was on a 1-2 mile 4% grade towing 7000 lb with no effort in 90°. I...

Revised Blackstone report based on make, mileage and usage. They must have lost my particulars for the initial report. As yo can see they say it tests out very good compared to 38K miles samples! I only had 18K..... I guess it kinda throws that old ATF temperature chart in the garbage as I...

I just received a report from Blackstone on my ATF. Here ya go! Comments welcome as I don't understand it other than I needn't have been so concerned based on their analysis. Info missing so I will update but I surmise many here can figure it out on their own...

Thanks! I'm going to wait and see what Blackstone has to say about the health of my ATF. I've gathered adding the ATF cooler shouldn't void the warranty since it's built from genuine Toyota parts but IF I have an issue and had swapped ATF to another brand which I'm still confused about Toyota...

How did you come to this conclusion? My temps, pre ATF cooler install, were typical of the 2019+ Tundras so they'd all have to be sticking. It's running great! I suppose when I reflect it's the smoothest auto transmission I've ever driven (Aside from a 1969 Turbo-Hydromatic in my Chevy Van!)...

Elsewhere someone posted this tag for the 2021 Tundra. Toyota has removed mention of the "transmission oil cooler". That has to be some admission of "guilt" right there!

Toyota has always rated conservatively and says 10,000 lb towing capacity with 5.7L ..... I was more concerned with other models like Fords that states 13,000 lbs towing with a 3.5L! So I'm actually pulling about half of what a Ford 1/2 ton says IT can tow! BTW it has NO PROBLEMS towing! It has...

OK I messed up and was unable to edit the first post which should have said 260° was the highest I monitored. Pre ATF cooler install I was getting ~230° on 75° days going 65 mph (~2500 max RPM) on flats to rolling hills) AFTER adding the ATF cooler I am getting 180° on 100° day traveling up to...

Not sure what "normal" is with Tundras.... The heat exchanger is a small about the size of 2 tuna fish cans that flows radiator water to and from. ATF just circulates inside the heat exchanger. So you can't use it for a take off for an auxiliary ATF cooler. The pre-2019+ has the heat exchanger...

Yep! I'm not sure how or when the AC condenser option started but supposedly a change in the "freon" meant the could no longer use that design. So they just removed it! LOL! The idea we'd have blinked an eye that the Tundra cost ~$500 more but boasted a HD ATF cooler.... Supposedly the over...

That's the same wording for the 2019. Trust me...there's NO ATF COOLER on a 2020 or a 2021 either! Up to 2018 they had an ATF cooler of some sort. Again Toyota engineers are complete idiots when it comes to cooling ATF. What could be easier than some lines to an auxiliary cooler? A guy on...

Yes 2019 and 2020 they removed the ATF cooler. Previously it shared the AC condenser or some such idiocy. Toyota engineers are complete idiots when it comes to ATF coolers! They refuse to simply look at the proven correct way to do it and end up with "pink milk shakes" and other nonsense.

If you have a 2019+ Tundra with Tow Package I'm sorry to say it does NOT have an ATF cooler! Mine has the tow package and sticker says "transmission oil cooler" on the paper work I have. It has a heater/heat exchanger that in recent discussions Toyota has started referring to as a "cooler" but...

Dang it!!! 260° Can't seem to edit the post... sorry for confusion!..

Hi, I have a 2019 Toyota Tundra with tow package which was supposed to come with an ATF cooler as per my list of options. Many discussions has Toyota saying "not needed". I wasn't towing until June and since put about 3000 desert and mountain and 100°++ days on the road. I had topped it off...
