2019 5.7 trans cooler location

I set up OBD Fusion and paid the extra $10 as well. Engine oil is right in the list of selectables. I’ll share a screen shot.

 

Has anyone done a external cooler retrofit on their tundra yet?

 

I've been following this thread, kinda freaking myself out a bit..."oh no, my new baby (I love this truck) may be defective? Say it ain't so!"

Then I think: It's a brand-new 2019 with only 3000 miles on it so far, half of those were towing miles already. The factory/dash temp-gauge barely rises above the middle mark when going uphill with the trailer and it's a Toyota and it's got a factory Warranty.

If 240 degrees is as bad in actuality as it is in theory in these transmissions, I think it would fail within the Warranty period, right? 3 years of towing @ 240+ would surely cause a failure of some kind, right?

F'it, I'm going to trust Toyota & rely on that Warranty. If she dies, she dies. Best case, nothing goes wrong. Worst case, get the trans swapped & trade it in having learned a lesson....or....Toyota makes it right & gives me/us a cooler after they fix the damage.

Let's see what happens

 

You'll find this forum can quickly become an amplified echo chamber, where a post about a minor drivetrain change by Toyota quickly becomes "My transmission is in full meltdown! Argh!!!!".

 

UNLESS...Toyota has already put hundreds of thousands of test miles on 2019/2020 Tundras, and they know that under nominal towing conditions, the normal distribution of transmission failures median is at 38 months, and that one standard deviation is two weeks. In other words, that could be an optimistic assumption.

 

Warranty for drive train is 5 yr/60k. I had a transmission fail at about 59k on my 2010 and it was replaced under warranty. Still had issues after that until i traded it in at about 94k.

 

I was just messing with @CO_Native.

My point was Toyota ALREADY knows they aren't going to be replacing every transmission under warranty. Hopefully, they have considered the towing owner's wallet as well, but that may be further down their priority list.

 

I'm with @JohnLakeman on this one. I suspect the transmission won't fail in the first 5 years/60k miles but I also suspect it may have a lower probability of making it to a million miles than pre-2019s.

 

Sooo who’s adding an air cooler to a 2019-2020? Didn’t someone post on here they had all the parts just waiting for warranty to expire?

 

You have a transmission temp guage on your 19?

 

what do you think? Of course not.

 

No, I said the "factory/dash temp guage".

I assume it's a measurement of the cooling system as with any other vehicle, not necessarily transmission.



That said, since they're "integrated" now, might it be fairly safe to assume that gauge is a rough estimate of the overall conditions, including the transmission?

 

That is your engine oil coolant temp. Not the same as ATF temp from the pan.

 

Actually, there is no oil temp. The gauge above the circled one is the oil pressure.

No, that would not necessarily be a "safe" assumption. Most of this thread has been about the cooling requirements of the transmission (ATF) exceeding the capacity of that little warmer/cooler under heavy towing conditions. Tundras driven in town as daily drivers probably won't have a problem.

 

Fair enough, I learn something every day.

 

TundraDude34 posted a video on YouTube a week ago. Mike Sweers Chief Engineer at Toyota is building a 2020 tundra. Has already done suspension and wheels and tires, said SC is coming. I bet his truck will be getting a real air to fluid trans cooler!

 

Or maybe he knows there is no need for one.

 

Yep. I’m thinking of taking mine off my 18. It’s just another part that adds to global warming. I mean if these transmissions can handle 240+ regularly then why did every previous year have one. Seems like it was a waste of money.

 

i see what u did there, lol....

 

He’s got an excellent point though. Most Toyota fan boys on here just aren’t willing to admit that Toyota might have made a trade off

 

As a long time Toyota fan boy, I too question the decision to remove the transmission cooler, especially doing so without any explanation when current users are seeing operating temps far beyond what are normally considered contributory to longevity. It doesn’t make sense, and as this thread proves, it creates a sense of doubt that Toyota doesn’t seem to want to address.

 

Oh don't get me wrong I wish my 19 had the same cooler my 08 had. I was simply suggesting the possibility that the engineers at Toyota know something we don't.
I still haven't talked to my dealer about the possibility of adding an external cooler but plan on.

 

Maybe the engineers are Toyota are preparing for the 2021 model and making small changes like this for what,s to come. I seem to recall that the 2016 or 2017 tundras have a spot on the fuse panel under the dash marked led lights, but there were no wires connected to anything, then in 2018 bam LED headlights, I dunno just a guess.

The 2015 tundras have all the holes located for the 38 gallon tank but only had the 24 gallon tank, then in 2016 bam 38 gallon tanks.

 

I'm honestly waiting for someone to go ahead and do it themselves and make a DIY thread. Once that happens, I will jump on the wagon and do it as well.

 

I doubt you'll see many doing it unless Toyota okays the warranty.

 

If I had a 19 I’d also think about adding one if I towed a lot. I think Toyota is taking their chances with the less than 10% of owners who actually tow. 90%+ will never have an issue or probably even know there isn’t a cooler. But I’d worry about longevity.

 

Someone should get their fluid changed and analyzed. Especially if they tow a lot.

 

Has anyone gotten a straight answer from Toyota? I opened a case to ask month ago or more and was told it is what it is. Was hoping someone got a better answer than that.

 

There is another user of this forum who is pursuing the same course. Without significant failures that can be attributed to the temperature of the fluid, I doubt Toyota is going to budge. The gen4 is coming soon and that will be their focus. Good luck and keep up posted.

No gen 4 until winter 2021 I saw
