2019 5.7 trans cooler location

iirc, tow-haul will hold the gears longer which helps but it would be a good design if for example blocked the od or 6th.

 

Well, you don't know that will be the result...you only have 7K miles on your truck. But, at 20K...?

If you had sent this sample in, and it came back looking good, you could take another overflow sample at 20K for testing. But...if the report had came back only OK, and showing oxidation, then you could either let it ride to 20K for another overflow sample, OR, do a drain and fill to insure you get the metals off the bottom. Starting over with fresh fluid, you continue to take samples and test at smart intervals until you begin to understand how long your fluid is going to last at the temperatures you have. If you get where you believe 60K change intervals are OK, then quit worrying and sampling, and have the dealer do the recommended 60K fluid changes.

If this report had come back poor, and future reports at regular intervals show continuing fluid degradation, then it would be time to think about taking actions that could interfere with your warranty, and NOT be thinking about 5K mile change intervals on WS imo. But, if it's going to take 5K mile change intervals to keep your fluid fresh, then maybe that would be cheap insurance to keep your warranty in effect. Before I took that path, I would definitely understand that it had to be done.

 

I tow on s4 and tow haul on , my gears definitely hold longer And you can feel definitely a difference. The s mode (selective mode) Works exactly as D except if set to 4 it won't go to 5th or 6th gear and give you the ability to manually control shifting . If I go to 5th gear my trans temp creeps up , found s4 to be best and I keep my speed between 55 and 65

 

This video tries to rationalize why the cooler is gone. He claims the temps are the same, but aren’t they running 20 degrees hotter?https://m.youtube.com/watch?v=VZSt7cs7Iyg

 

Cost cutting plain and simple, Toyota is not going to come out and tell you the truth on this. They give a BS answer like they gave the guy in this video. We have already seen really high temps on non towing trucks, that were not that high previously. Even mine with the cooler I still felt ran to hot for my liking. I guess you 2019-20 guys run em hard so if you smoke the trans its under warranty.

 

Mine is reliably 30 degrees hotter than the temp in my 08. I do the exact same drive a few times a month.

 

Right now Toyota parts catalog shows the transmission is the same between a 18 and a 19. I assume it is wrong or this dude was fed bad info.

I want to know what they “optimized” with the coolant exchanger to justify removing the air cooler. To me, optimized means something with that heater must have had a design change. If it didn’t change (same part number) then that whole email reply is just a bunch of B.S.

If it isn’t compatible with the old thermostat we’re all effed and won’t be able to add a cooler at all unless we buy the old coolant exchanger as well. Assuming the transmission is exactly the same as 18 and earlier models.

 

Does anyone have a way to contact Toyota corporate? I want some better answers than I’m getting. At the very least I want to install a better cooler and not void my warranty.

 

Why was the cooler at the 1:15 mark of that the vid shown as suspect?. I noticed that when i was looking over the truck before i bought it, and didn't know what it cooled. Now that i had the chance to look and trace the lines, it seems like a P/S cooler, is that correct?

 

I posted this before... sorry for those who have seen it. The heater/cooler is the round device with cooling lines

 

That video didn’t really say anything and the Toyota email was probably written by a lawyer. Never seen his videos before.

 

It looked like the ps cooler to me too, but he said something about new lines from the radiator. Not sure what he was talking about.

We need to ask Toyota why does the ps need a cooler and not the trans?

 

The way I read that vague "optimized" comment, it was not for the air-to-fluid exchanger that is missing, but as applying to "optimized" transmission operation, which is bs imo. Not much they can do to make the transmission "run cooler", and still do the same things it was doing prior to 2019.

The transmission warmer/cooler is the same part number from 2018 to 2019, so the thermostat (pre-2019) should fit just fine with the existing warmer/cooler. The fact that the parts listing fitment shows the thermostat fitting a 2019 is engineering's recognition that someone may want/need an air-to-fluid exchanger on their 2019, and this is tacit approval for a retrofit imo. Service/warranty may not see it that way if your transmission craters for other reasons.

 

I'm still tripping on the entire process.

Suits: We need to shave a few $100 of production costs
Engineers: We could completely redesign the tried an true transmission and remove $20 of parts from each vehicle. Go ahead and let it run hotter and have more failures within warranty periods.
Suits: Brilliant! Do it!

Tundra manufacturing is down to a science. They can probably manage production costs down to pennies. Service not so much.. When I wanted Toyota to show the ATF cooler I had 3 techs tied up for 30 minutes trying to figure it out... If any solutions presented added 1.5 man hours to the assembly of the Tundra there would have had to have been a helluva good reason!

When people think durability they think Toyota! It's THE one thing that makes them better than the competition. How many would have gone with a Ford if Tundras were crapping out at 80,000 miles? ALL OF US! We got Tundras as we can reasonably expect 10 years of trouble free service. The transmission being the most expensive and sensitive component and least serviceable..... Last thing I would consider messing with!

As per fitting the '18 thermostat, lines and remote ATF cooler... why not? Looks easy to put on. I highly doubt it would be something they'd check for during normal service. Easy to remove if issues crop up.... Again that's a $5 molded piece of steel! They charge us $200 but not what Toyota would be out for each piece. Those puny coolers they did supply couldn't have cost more than $20.....

IDK... I'm still trying to wrap my head around the logic of this IF it's bad move...

BTW I sent off an email to Toyota politely asking about this and got an obvious redirect that did not mention my concerns at all but a link for formal complaints about the dealer!

 

Well, if Fords and Rams are in the shop until 45K, and then crap out, would this answer be any different? It's like I said before, if there are two guys running from the bear, i.e. Toyota only has to be more durable than Ford and Ram. Maybe Toyota is deciding they're just too damn durable...maybe they're making a few changes to absorb increasing regulatory costs, and taking a little hit on durability. Doesn't change their profitability short term if your Toyota only lasts 150K miles.

Toyota engineers are whispering in your ear, Greg..."If having an air-to-fluid exchanger worked when towing before, it will work now". What you should be thinking about is if DOING NOTHING is a good move.

When I buy a Toyota, I never worry about living 50 miles from a dealer, because I never expect to take that Toyota back to the dealer, EVER. I believe my Toyota will NEVER require major repairs, or that I'll be victim to those little pissant ankle-biting issues requiring a dealer next door. (Seems contradictory, I know...an optimistic paranoid). When I get a Toyota that proves that wrong, so be it...I'll crank that into the next purchase.

I am paranoid about letting other people work on my car. Not taking vehicles to dealers for service has worked for me for decades. The only time I've had repeat issues is when I actually did have a major problem (GM, not Toyota); not long after the repair, there was another major problem in the same general area of the previous repair. Dang suspicious, that. At least it was all (barely) under warranty.

 

You're missing the point...a couple of pen strokes could have saved MORE!

Face it Tundras payload is under rated and another feature they fall behind Ford. They could redo the numbers with a different formula and increase payload to match Ford.... Cost=$0!!! In fact MSRP would increase!

Has same benefits of probably still out lasting Fords etc.... yet "failing" just outside of warranty...

It is IMPOSSIBLE to predict transmissions won't fail till out of warranty nor still outlast Ford by 1 mile! They don't work that way! They have to be built to extremes and hope for the best. They are a KNOWN technology. You could drop a 1969 turbohydromatic in a vehicle and easily claim 300,000 miles no problem. Strat making changes and pulling parts out and all bets are off......

Since many Toyotas get traded in before warranty up this means Toyota will be inheriting any long term issues not avoiding them...

They had to be a couple guys thinking like me and since the other side of the table is stuck with "we're only saving ~$20" per vehicle...... in fact less because now you have a team analyzing it! How could it possibly fly without reams of research and data?! Research is not free!

You want to save $20 per Tundra I can come up with a lot more ideas. How about just putting air in the tires instead of nitrogen?! Who's even gonna complain or notice?

Further the ATF cooler could be an upgradable option. "Hey guys for another $500 we'll add this high performance ATF cooler".....

I'm just trying to work through the logic of removing an ATF cooler... Would I like to see it? HECK YES! But lack of one is not proven to be a bad idea..... yet....

 

I think you're missing the point. Toyota is an autonomous corporation. They have decided and made their policy. You can't change that, or retroactively re-think their thinking. They have millions of customers who affect their sales, but for the customer base to change their thinking takes a LONG time and a gazillion "Aw, ****"...just ask GM. YOU will have to adjust to Toyota's policy as best you can. Their engineers have even given you a head gesture on what it will take to do that.

 

Their policy is to make money!

Aside from that what policy are you referring to?

Do you really think they have decided to cash out and start making junk and living off their reputation now?

GM is a totally different beast that struggled for YEARS and has made few vehicles that rival Toyotas in any class. Their model proves the folly of shaving too much off; pandering to a lower denominator. While Toyota has made some drastic cost reductions moves like plastic beds in Tacomas they have kept the bread and butter drive train top notch. They KNOW which side of their bread is buttered!

I'm not wholly disagreeing with you but it so severely defies logic despite other manufacturers pulling similar stunts.

Look with the 2021 or 22 Tundras being rumored as new model they will be getting TONS of these WITH warranty in tact trade ins. I'm a guitar player artists and can see the problems just removing items and retooling and can easily see it doesn't save any $$ and with retooling, re-engineering be argued to cost more! Coupled with risking premature failure of an expensive component......

SO many other cost cutting measures a fool like me can come up with....Bottom line is an ATF cooler is not expensive! Remove the PS cooler and risk that going out instead! I didn't even know PS had a cooler! Can't monitor PS fluid temps....

 

Unless a corporation is a charity, all corporations have making money as policy. Well, scratch that...For successful non-charity corporations, the PRIORITY policy, the reason for existing, is to make money.

The policy I'm talking about is sacrificing a little bit of durability in order to reduce production costs...which doesn't necessarily translate into making MORE money. It may just be offsetting increased costs of features demanded by the government and customer base. Maybe they'll sacrifice just enough durability to be more durable than Ford, GM, and Ram. (Whoa...standby, much more bad news on the way!)

Anyway, I've tried to explain my perspective from a engineer's point of view, and as a 30+ year Toyota customer, and you're not buying it. You'll have to make decisions for yourself and your tow vehicle as you see fit. Continuing to worry and wring your hands about the status quo, however, will have no affect on the future outcome.

 

But you've offered no evidence! Pure speculation which in the light of my uninformed suggestions don't hold up!

Seriously! Consider how many other components could be removed or cheapened with similar costs saving?

The idea they can target a transmissions life based on letting run out of spec temperatures is nonsense! can't be done...poor bet!

The idea of thinking Ford et al has peaked and you can start moving south on longevity....another poor bet!

Standing pat makes sense! Toyota only sells ~100,000 Tundras per year. IF ATF cooler costs Toyota $50 that's only $5M savings....Now figure retooling costs. Engineering costs. Reliability risk management.... There's no profit there! Risking a recall or massive warranty extensions......

Fact is you're simply not presenting an argument of any kind based on fact or logic but purely emotion....

Please I NOT arguing with you but countering the points you've been kind enough to make with top of my head logical reasons against.

if you can refute any of my arguments I'm all ears.

BTW I'm in the "don't worry about it" camp. Curious but not concerned...

 

Yeah, sorry, my crystal ball is broken, but your engineering/automotive manufacturing arguments are all weak...as I would expect for someone uninformed and inexperienced. Stop trying to talk yourself into another reality; you have to decide if Toyota's change will significantly reduce your truck's reliability while towing, and live with the consequences of their actions.

So, if you're only curious, but not concerned, I have no need to beat you into verbal submission with argument. While I am also "curious, but not concerned", I can afford to be since I have a 4.6L sans tow package, and I don't tow.

BTW, you may not have been born in the mid-fifties, but GM was at the absolute peak of automotive innovation and quality for the time. They really didn't have to do much to be "better" than the Fords and Chryslers of the forties...remember the bear argument? Joy in the fifties was a vehicle that started quickly on a cold morning, and could be depended on the start fast every time. They drove well, rode like magic carpets, and would blow the doors off anything else on the road. That was a long time ago.

 

Now back to some data feed , I am seeing the below temp driving with outside temp at 60 , let us say I wasn't quite gentle on the paddle but nothing crazy either

 

And that is without towing , when I tow my TT 4200 pounds , I see 215-217 average on pan and same on torque , I tow on S4 and tow haul on , these are mainly flat and also going up some Vermont hills

 

If my arguments are so weak as you say it should not take much effort to refute... yet you have not presented any counter arguments.

Every engineer I know with 30+ years of experience thinks logically not emotionally and you've yet to exhibit any logic. BTW While I am a simple artists for money making purposes I have an MS in geoscience so have a pretty good understanding how systems work and more to the point the scientific method. And can spot a fraud from a mile away.

Prove me wrong with facts an data not anecdotes and emotion and we can continue....

 

Look I'm an engineer!

 

Facts are:

1. If we can use a little scangauge to read the trans temp, so can Toyota. I am %100 sure they know the trans temps with their fancy computers (especially after a major redesign) much better than the little scangauge can. lol
2. Trans temp are running 20-35°F higher on average and in some cases (e.g. towing) even higher without the air cooler.
3. Even with trans air cooler in older models, some people didn't like the "high" trans temps ... including me.

Less likely scenario:
Huge miscalculation to remove the atf air cooler and it will be recalled.

More likely scenario:
Toyota thinks (refer to #1) that trans will do fine with higher temps.

 

Another scenario: change to Freon necessitated a change to the cooler/ac condenser and Toyota felt a truck on its last 2 years didn’t warrant redesigning a new atf cooler and will take their chances with the few that fail.

The separate cooler from 07-mid 10 probably doesn’t fit due to change in grill and hood.
