‘19-‘21 Tundra Transmission Cooler deep dive plus how to add one!

[@joerivas9847]

A vehicle is NOT an investment, its a depreciating asset. BUT still do what you can to make it last. Just bought a 2017 Tundra, hopefully the LAST truck I buy, am 62 years old now.

[@DirtE30]

Sorry for the low res guys, for the life of me I couldn’t get IMovie to let me upload or save the 1080p file... and the backlighting, sheesh...

[@MrTaylorcraft]

Where do you live in Kentucky? How much would you charge me, to put this on my 2019?

[@EverydayJ1786]

Good video . Coming up on 1 year for me running a cooler on my 2019 . Imo if anyone tows with their Tundra this is a must

[@imrikkibobbi]

at this point i'm only towing a jet ski, when you say towing like a 5th wheel or camper or anything with significant weight vs 1 jet ski? i'm a brand new Toyota Tundra owner so i'm trying to be informed as best I can, thanks !

[@davidwelty9763]

Great video. I think the Toyota engineers knew their business. It has been long enough since the deletion of the trans cooler that we would have heard of massive Tundra transmission failures by now. This has not materialized. Toyota is too hyper vigilant about their reliability reputation to do something reckless.

[@joerivas9847]

Yeah right. GREAT job on the frames!!!!///

Parts list: Please note that I have zero affiliation with any of these... This is simply what I used, it is in no way a recommendation. Proceed at your own risk, as sad as it is that I have to even say that.

Can use push in AN -6 female fittings readily available anywhere. I didn’t go into detail on where and how I mounted my cooler, I will try to capture that in detail in a future video.

[@montanamike3688]

Thank you for making and sharing this video.

[@DirtE30]

Very welcome

[@dalephillips8250]

Thanks for taking the time to make these videos....they are an extremely good guide which I will use if and when I add this to mine.

[@lrcreamer]

I purchased the genuine transmission cooler kit for my 2021 tundra..came with the same Toyota valve but also included original Toyota hard lines and a cooler…must have if you tow

[@danbaxa]

Lawrence, What did that cost you? I just got an estimate to that job from the Toyota dealer where I bought our 2021 Tundra. 6.5 hours labor and $ 2000 for parts. I don't think that includes any Vaseline. They also said if I didn't use all the genuine Toyota parts it would void my warranty. I have about 16k miles on our SR5 DC that I do use for towing. Thanks in advance.

[@lrcreamer]

990 dollars kit from genuene tran i did the work step by step process on you tube

[@danbaxa]

I did get a call back from the dealership saying they had made a mistake on the estimate. Said they priced the job for a 2022 rather than a 2021 and that if I could come up with parts they could put them on in 1 hour. ?? Thanks for your reply!

[@gatornation3889]

I have a 2016 Toyota Tundra crewmax 4x4 and lucky enough to have the cooler, I am disappointed that I do not have the trans temp gauge. Thank you for this video. We installed a cooler on my buddies 2020 TRD PRO using your advice, just wanted to say thank you sir.

[@vxphan2601]

Thank you for the video. Very clear explanation. So. We have to put the pin back when we change out the transmission? How hard is it since we don’t have the space around to do it. Not very good design from Toyota Can we just leave the pin in it to keep the flow path open at all time?

[@gregkeller80]

Thanks a bunch! Gonna do this to my 21’….I’m pissed the deleted the zerks on the drive shaft as well. F’ers!

[@marshmower]

It's a slightly different part for the 4.6 4x4 which also didn't get a cooler starting back about 6 years ago. But regardless of model, lines can be attached directly to the trans. If you do that, bypass the coolant line. Otherwise they should have used a much bigger heat exchanger to keep the temps stabilized. Probably the fact that companies assume the end user is a dumb bag of cells.

[@rickycantu519]

i seen a video with a tundra going up the gauntlet in colorado and toyota said 246 degrees is normal for the transmission?

[@pecosb5221]

Thank you for the video but how much fluid did you added? And at what temperature do you open the level plug? Tks

[@benjamincarter9726]

Nice vid! Thanks, debating adding a cooler to my 19! Tundra

[@thomasdean5651]

Sounds like you routed the hoses without removing the skid plate. Is that correct?

[@hugosanchez-blanco4649]

This is a great video. It is exactly what i need and what i was looking for my 2018 Toyota Tundra 4.6L SR5. Thank you. can you show how to run the new hoses under to the new cooler. Than you..

[@DavidPrater-c1j]

Were can I buy the thermostat plate so i can install a cooler??

[@kmalerich]

Toyota screwed the pooch on the trans cooler issue. They will likely pay dearly for the mistake of allowing the bean counters to decide their engineering requirements.

[@lanceshier741]

Follow the money

[@thomasdean5651]

Question from a novice....after installation, there will be trapped air in the hoses and cooler....is that not a problem?

[@johnspitta6725]

14:06 Parker 801 Pushlock hose.... Is this the one? Specs look good. 801 Hose | 801-6-BLU-RL

[@DirtE30]

Yes that would work. It’s a blue color though. Not sure you want blue? If you just want black, it would be 801-6-BLK. Look up your local Parker Store, they should stock this.

[@binhlam410]

How’s the transmission cooler system doing? I’m thinking about getting one too

[@johnspitta6725]

Howdy. I'm in the middle of my install. I'm probably over thinking this. I assume the cooler is itself doesn't have a flow direction. Meaning. Fluid coming in and Fluid coming out could go either way. I'm pondering something.

[@DirtE30]

Doesn’t really matter but gravity is what it is as far as any entrained air.

[@vzangla]

sounds just like my 2020 like a damn diesel @18:44 what is all the racket?! thanks for the video just bought all the stuff.

[@DirtE30]

Lol… go hold your phone next to the oil pan of any running engine and report back…

[@groth3395]

what is the purpose of the little pin? This is not clear to me. Sorry if I'm dense.

[@DirtE30]

The pin is a manual override for the trans cooler thermostat.

[@groth3395]

@@DirtE30 Yes I realize that. But is it removed after filling / checking trans fluid?

[@DirtE30]

@@groth3395 oh sorry, yes, once you’re done, you remove the pin holding in the thermostat. It will then operate as intended and open at around 195f to allow circulation of the fluid to and from the external cooler.

[@truthjustice3313]

Great video. I had a 2016 and now a 2021 that I need to do this on. Can you confirm which of the two hose barbs on the thermostat cooler assembly is the output? Is it the top one aligned with the pin or the other one? I want to ensure that the output is installed on the bottom of the plate cooler. Also, is it ok to install everything totally empty and then top off fluid level in tranny plug? No concern with air bubbles / pockets? I'm still trying to figure out the best way to estimate the quantity of additional fluid needed. Thanks!

[@DirtE30]

It’s the one nearest the pin. The way I determined that was to pre fill the hose/cooler assembly and then pour it out and measure what comes out. Then add that amount after install. Won’t hurt a thing to install it dry.

[@truthjustice3313]

@@DirtE30 Great thx for the quick reply. I'm going to use DeRale HD hose the entire way as well instead of messing with the metal lines part of the way. Less connections and potential leaks. And using the Hayden 679 cooler. Should be a more efficient cooler than my OEM 2016! Thanks again.

[@DirtE30]

@@truthjustice3313 should be a solid setup. I’ve used that cooler before on my ‘19, was happy with the performance for sure.

[@pecosb5221]

The most important think is running low of fluid too

[@g2theb584]

Thankful I got an 18 when I did.

[@floridalife7564]

Yea me too

[@davydawg01]

What diameter of hose did you use? How much transmission fluid did you end up having to add? Thanks for the videos! Much cheaper than other alternatives, and a much easier install.

[@DirtE30]

It’s 3/8” ID hose… as far as how much fluid it’s probably half a qt or so, I just had the dealer top it up the next day. It’s not enough to be of concern.

[@josephmartinez8786]

How many ft of hose did you use

[@DirtE30]

15’ or so

[@felixlavallee7146]

can you give us the parts names ? im havin a 2020 sr5 in Quebec , and i want this setup . thanks for the video all is clear.
