2022 Transmission Cooler?

I haven’t had the chance to get my hands on a 2022 just yet to confirm. Does the 2022 Tundra come with a dedicated transmission cooler? Has anyone monitored their transmission temperatures while towing, off-roading, etc.

If the need for a transmission cooler is there, I’ll be happy to design a transmission cooler kit for the 3rd generation.

 

...and here I was all ready to say "Lord not another transmission cooling system thread...." but you addressed the problem AND are presenting a solution.

Hats off to you, good sir.

 

Yes it has a dedicated transmission cooler.

 

Good to know! Thank you.

 

Thanks Nick. I love the kit on my 21. Hopefully the new one doesn't just have a puck.

 

Anyone happen to have a pic or parts diagram? Been poking through pics and such now that I have ordered a 2022 and can't seem to find a picture of the cooler anywhere. Just curious as to size, if it is air to oil, where it is located, etc.

 

OEM location is typically within the radiator.
That would make it a liquid-to-liquid exchanger.

One integrated in the lower part of the radiator and one “puck”.
I assume you work for a dealer to get those pictures?

 

Awesome. Thanks for sharing. Very different than my 2008 Tundra (air to liquid in front of radiator), 2015 Tundra (air to liquid above of ac condensor) and 21' Land Cruiser (air to liquid similar to 2008 tundra). Good info!

 

Thanks Ryan! Sorry to have to ask it here but maybe you could help me find the answer. Do you know if the rea overhang is the same on every version of the 3rd gen Tundra or is their one configuration that has the least amount of rear overhang (distance from the back of the rear tire to the back of the rear bumper). Thanks!

 

If you check the difference of the overall length and wheelbase on toyota.com for both wheelbases you get the same value. Knowing the front doesn't change you can safely assume the rear wheel to end of bed is identical on all variants.

 

Thank you. I had observed what appeared to be some inconsistencies on the US and Canadian sites so I wasn't trusting their dimensions. I either misread them or they've been updated.

 

Good info here, looks like its not a stand alone cooler like we were told it was or many said it was going to be. Wonder what the temps are gonna be, hopefully tfl offers insight when they test there's.

 

I don't consider that a stand alone cooler, it's running next to the engine coolant passages within the radiator. The early gen 2 tundras had an actual stand alone cooler, my 2012 Tacoma has a stand alone cooler. 17 tundra has the integrated cooler and she runs hot when pulling, this will probably be the same.

 

Most other manufactures use an in the radiator cooler. For a stock vehicle that is more than adequate due to the amount of surface area it has.... however... when you started adding high stall converters and making more power you need the capacity of a dedicated cooler in front of the radiator.

 

I agree with you other manufacturers do not that doesn't make it right. TFL I think had the f250 and Silverado with these similar trans cooler designs overheat on them. Temps run higher in systems designed like this just a fact. It is probably done for cost savings more then anything. My tundra had the combined setup and that thing ran hot pulling a trailer, I suspect this one will as well.

 

Your tundra has a combined system like this? FIt wasn't in the radiator on the 2nd gens(14-18)

I do agree with you an independent cooler is always going to be better, but the system where it runs to the radiator is much better than the crappy system on the 19-21.

 

Yeah mine isn't a stand alone either, 19-21 got rid of it altogether and have nothing at all. I think it was pre 2014 that had the actual stand alone trans cooler.

 

Well apparently the integrated liquid-to-liquid cooler works better than no cooler on the 2.5's. TFL did a re-do of the Ike Gauntlet run with the 2022 in tow + mode now and tracked trans temps with a scangauge. The 2022 3rd gen showed 231 F peak temp at the top of the Ike pulling a little over 8k lbs vs 246 F on the gen 2.5 without a cooler. Video link timestamped to the trans temp discussion.

Of course this is a whole new transmission and cooler setup so I make no inferences as to if the cooling is "sufficient" and since I don't tow up the Ike I have no idea what temps that means I would see towing a race car on an open trailer (5k lbs) on the barely hilly (but hot and humid!) terrain of the south east but since it is at least some information and a reasonable comparison point to other TFL tests I thought I'd share. I also have a 2021 TRD Pro with no cooler and have a deposit and deal worked to trade it on a 2022 supposedly coming in mid Jan so I am mildly interested in the trans temp "issue" but really like seeing improvements in overall towing performance. That new engine sure looks like it is loafing along and is torquey and quiet!

 

You have to also compare the outside ambient temps for the two as well. The 3rd gen they were pulling when snow was on the ground so I would expect that temp to be higher in the warmer months. I can't remember what the outside temp was like for the 2nd gen pull. Great that tfl is going to start tracking temps for us now, they should also include the outside temp as well for comparisons.

 

It was low 50's at the top for the 2nd gen pull. Timestamp video shows outside temp in dash. Not perfect comparison, but better than apples to oranges that often comes up on the internets...

So for gen 3, toyota boxed the rear frame and re installed a trans cooler.

Never ever fall for the “trust the engineers” BS again

 

Keep in mind most of the 10 spd transmissions in the competitions trucks use a full synthetic ATF, I wonder if Toyota stuck with the old WS ATF for this 10 spd too, I’m guessing not.

 

Of course they could have down shifted and kept there trans temp down even lower. All these tests are in D.

 

Right... because a completely new design is what should be compared to an outgoing dated design. By that logic they never should have had a V8 either because they got rid of it in the new design. You should only "trust the engineers" if you are using the truck as they designated in the first place. Read the manual on the 2019-'21 (and probably the '22) and you'll see that they say it's primarily a passenger vehicle with some towing capability. The engineers built it to that spec. and the payload ratings show it. Then the marketing monkeys do what they do best and lie as legally as possible to advertise it in ways that it wasn't strictly designed for.

The point is, the late model Tundras were never designed to be a towing monster/work truck every day of the week. That market segment is owned by the big 3 and Toyota isn't gunning to unseat them because they aren't going to play to the "I want it all" crowd. The Tundra is for people who OCCASIONALLY need a bust ass tow rig or to move something a bit heavier than a midsize can handle, but not every day. The fact that they aren't designed for that and still have stellar reliability after people go off thinking like cavemen "Truck has bed. Bed mean tow. Tow mean haul 50 foot trailer to compensate for tiny dick." and run the trucks harder than intended is a testament to the designs.

Yes, we all miss the coolers. Yes, we all wish they hadn't removed them. Yes, we all think that having the cooler would have been better for the trucks long term. And, Yes, this is a dead issue that people still insist on whining about and it's getting old. It's been resolved. Add a cooler, or don't, but FFS quit bitching.

 

I really don't think its a big deal with these modern transmissions. The Ford 10 speeds get that hot too, even in the Superduty. I wanna say the F250 with the 7.3L Godzilla might have gotten up to 240F when it did the Ike so they clearly don't care if they are letting the Superduty do it.

And I think a lot of it has to do with how they tune the torque converter. All the Toyota's I have ever driven were super liberal about unlocking the TC which is how you generate a tremendous amount of heat.

The F150's, at least my 2014, almost never unlocks the TC in T/H mode.
