You and me both. No idea who that guy is either.

I believe yours will still have the thermostat mounted on the transmission, where mine is, saving you that component.
Yeah - it’s 30k for maybe my $5 Dex VI … but after the initial pan dump (around 20k) … I‘ll be going longer with that ZF unicorn tears stuff - $20/quart on eBay - and Mopar is $30 …I am a strong believer in the WS Lifetime Fluid. Lifetime is 30K and WS is Idemitsu or Maxlife.
Half these Bubba drivers don’t know the ST tire speed ratings eitherThis is a hotly debated issue…
I own a 2020 Tundra and have been presented ZERO evidence compelling the argument one way or the other (IN MY CASE). On a few rare occasions the temp has spiked to about 230 ish however the temps drop extremely quick so in my opinion the puck is doing something right.
I have done a ton of research on the subject. The pre 2019’s with the factory installed coolers are usually within single digits of mine (in some cases as little as 4 degrees). Yes heat will cause a transmission to break down sooner but I don’t buy for one second 10 degrees is going to have the same transmission die at warranty’s end vs the 250k + of a cooler installed one. Life time fluids is BS which goes to your point OP about not trusting manufacturers.
There are many owners installing aftermarket coolers which are lowering the temps past that of the factory installed coolers. They are much higher quality and have larger surface areas hence the better performance. NO ONE addresses this PERIOD, it gets completely glossed over. Again these temps continually get compared to the puck version of the Tundra. That’s a inaccurate comparison and simply a misrepresentation of facts.
Speed is another factor glossed over. The Tundra manual states 65 mph max for towing, I have never had any problems with transmission temps at that speed. Many people balk at this. It’s highly common to have a 1/2 ton towing a travel trailer at 75 mph + in the left lane flying past you in my area of the country. This will kill a transmission but it doesn’t stop anybody from driving like that.
I drove commercial trucks for many years and dropping a gear in the mountains greatly helps to reduce tranny temps and keep them in check. Same goes for my Tundra when towing.
No black and white answer has been presented. In my honest opinion it’s a case by case basis. There are some that would benefit and there are some that would not.
Thanks for the reply! Yeah, as I said, I have a "glam truck" and she does little to no real work, I don't drive a lot so I think my plan of new WS fluid every 50K sounds reasonable, and should the transmission ever give up the ghost it will still be under warranty.This is a hotly debated issue…

The head engineer for the Tundra. Somehow he has a weird "following" in the Tundra community and he belongs to a few Tundra FB groups. I do not have any idea who the lead engineer was for any other vehicle I've ever driven but I know Mike Sweers.I may be stupid but who is Mike Sweers?
No problem, I plan to do the same or 40k fluid changes because it’s my weekend/family vehicle. Won’t hurt and doesn’t cost that much. I have a 10 year Toyota warranty that I purchased through a different dealership than my purchasing dealership. It was 65% cheaper…. So my transmission is covered as well. I am very interested to see how this all plays out. However I have yet to see a rash of failed transmissions. There are cases but some were heavily modified or severely abused (my opinion).Thanks for the reply!

Now that is a proper transmission cooler! Lots of surface area.View attachment 115051
Put the cooler on.
If you plan on keeping your Tunda long term the cooler is worth installing.
