2019 2020 transmission cooler missing

Temps under 215 degrees while Towing in my opinion are completely acceptable. Obviously the lower the temperature the better as heat is the number one Destroyer to Transmissions

 

Great info to share. I appreciate you posting that, can you get that yourself in writing that you are able to install an aftermarket transmission cooler onto your Tundra without voiding your warranty?

 

He's not correct. These are not the ATF temperature ranges. They are two separate temps that are conditions that set the code P0711. I wouldn't be using that as ammunition against Toyota.

 

why would I not want to use something that is posted in TIS for the transmission operating range? Yes it does say about setting a code, however it says that the transmission fluid temperature should NOT NOT be operating above 221 degrees Fahrenheit. Do you see the wording that I'm talking about? I have hard copies of it so even if they change it electronically I'm covered. And it's listed under the MY2019 Tundra

 

Just wondering, @sgtfluffy16 are you an engineer?

 

Not for a job, nor do I have a degree in engineering. But I have the knowledge of it. I've been building and tinkering and creating gadgets and Automotive since before I can drive. I've built a lot of my own Vehicles as well, including a 1951 Chevy pickup. A lot of the things that I did on that truck we're not the conventional things that everyone else did on that truck. But I built my truck stronger, to last longer, to be more easily serviced, and more reliable than what the normal AD truck builders did. Did I spend more time locating Parts, doing research, the initial fit of those parts, and spent a fraction but some parts cost more, absolutely! However, when it was all built, said, and done. My truck was more well-built than everyone else who just use the standard cookie cutter ways (s-10 frame swap) that everyone else did. And if anything ever needed replaced, we're service. I had full records of every receipt of every part on that truck. Plus it was easy to replace nearly every bit, of every part of that truck with off-the-shelf parts, not parts that had to be customized and made to fit

 

That explains it....

 

What does that explain?

That I am meticulous? Particular? Actually use the standard system of bolt torque yield specs of the bolts themselves and the substrate that it is attaching itself to, and torque specs how Vehicles were built?

 

I think what he means is that there is usually a disconnect between the Engineering (on paper) and the Practical application (Real world) and though both sides have merit and invaluable knowledge it is not uncommon to find that individuals tend to lean one way or the other. Though their expertise on one side or the other my be significant, it doesn't negate the other side of it. There has to be a happy medium, and approaching the problem from only one side may work, it is seldom the best/most efficient solution.

I may be wrong and @Moon Puppy can say so, but that's the vibe I'm getting.

 

Can we please get back to Rock Solid evidence of corporate kitty malfeasance, plz.

 

Can't help you with your poll question OP since I have no idea what my transmission temps are. But best of luck wit the good fight.

 

This is the description of what set the P0711 which you referred to previously. The code does not refer to an operating temperature.

MONITOR DESCRIPTION
This DTC indicates that there is a problem with output from the Automatic Transmission Fluid (ATF) temperature sensor and that the sensor itself is defective. The ATF temperature sensor converts the ATF temperature to an electrical resistance value. Based on the resistance, the ECM determines the ATF temperature and detects an open or short in the ATF temperature sensor circuit or a fault in the ATF temperature sensor.

After running the vehicle for a certain period, the ATF temperature should increase. If the ATF temperature is below 20°C (68°F) after running the vehicle for a certain period, the ECM interprets this as a fault, turns on the MIL and stores the DTC.

When the ATF temperature is 105°C (221°F) or more and the engine coolant temperature takes 10 seconds or more to reach 60°C (140°F) after a cold start, the ECM also determines this as a fault, turns on the MIL and stores the DTC.

I'm done with this thread. I'm just talking in circles now

 

I bought a Tundra because it cost less than the others and is supposedly more reliable. If it blows up while using it within the manufacturers recommendations I'll get something else next time.

 

Diesel is more of a slow burn. Yes it's an explosion but diesel does not explode. It's a slow burn. Gasoline explodes, and is much more flammable. This is way off topic though.

Back to transmission temperatures that are way too high because the external transmission cooler was removed on the 2019 and 2020 Tundra

Good update,

i have been watching this as it is going along as well. However first complaint, He is comparing Valvoline ATF to WS (world standard) Toyota ATF. The Valvoline may be a synthetic ATF but WS is NOT Synthetic fluid. No where in any of their composition states WS is a synthetic fluid

Your poll needs another selection: I will not be buying a newTundra

 

What do you drive now and what are you buying instead?

 

@sgtfluffy16 There seem to be a group of people who belive there is a problem and those who don't. I know from my own successful Lemon law case against Chevy (2017 Malibu) that Toyota is not going to release the info you are seeking. Chevrolet wouldn't even tell their technicians how many gallons were left in the tank when the fuel light is designed to illuminate - which they obviously know (long story and not the safety defect I had).

You should call your state Attorney General office and ask for an opinion about how aftermarket accessories affect the vehicle warranty in your state.

It seems everyone agrees that an aftermarket cooler is the best option to lower Temps regardless of whether there is a design issue or what the normal temperature should be.

Remember that if the transmission fails as a result of adding a cooler, Toyota would have to prove that it was the cause to deny a warranty claim on a transmission repair. If you have it added at the dealership it will be very hard for them to prove.... and then it's on the dealership.

If your light has been coming on without load or towing keep taking it back to the same dealer until they are sick of you and replicate the scenario and write down on an invoice that the vehicle was operating normally (while still under factory warranty).

As others suggested, the Toyota won't do anything until there are many failures and at that point they are probably most concerned about customer satisfaction and than other companies.

Try to get your particular situation solved and Toyota will have a record of it. Although I don't disagree with your temperature discomforts, you may be focusing your efforts in the wrong areas (saving everyone instead of yourself).... especially when some of everyone are picking apart your posts rather than coming over to my house and figuring out the rattling/clunking noise in the cab of my 07, lol.

Best of Luck

 

its overheating is what it is doing

 

the truck sits alot as i have a company truck. but bet me ill be into the dealer soon enough with a repair order about the high temps so it a legally noted

 

There is only ONE transmission thermostat for the A60 transmission and it is this one:
https://parts.toyotaofcoolsprings.c...9dHVuZHJhJnk9MjAxOCZ0PXNyNSZlPTUtN2wtdjgtZ2Fz

This thermostat will replace the spacer plate used on 2019+ Tundras. It is a Toyota engineered part, and is a simple bolt in installation.

Edit: Oh...Wait. Is the Hayden 689 one of those exchangers that bypasses cold fluid back to the transmission? You think you're going to use a bypassing exchanger in lieu of Toyota's thermostat? Dude...You can't even make connections to the A60 transmission without using Toyota's thermostat. I've had this conversation before, I'm done with this discussion. Read all the threads, the details are in the archives.

Installing that heat exchanger with the connections on the bottom is like putting an empty glass into a sink full of water upside down. Air will be trapped in the top of the exchanger because there is not enough flow and pressure to force all the air down to the outlet. The exchanger will then only be partially filled with fluid and will provide low cooling efficiency.

 

I also sued Chevy for a 2011 Cruze in a lemon law case. The earlier you get an issue documented, the less they can depreciate your car. I had my first issue at about 2k miles so when they bought it back I only lost about $500 and put over 100k miles on it. Cheapest rental ever! Get it documented as soon as you have issues and keep the receipts!

 

Toyota is not going to admit fault for anything. They ae not going to warranty a "modification" even if you use their parts. XOM is not going to give you specs on a proprietary fluid. I think it's a long road if you have issues down the road with the transmission. Fluffy might be pioneering the ultimate tranny fight, if its indeed a problem.

 

Do you realize how ridiculously easy this would be for Toyota to do in the event of a trans failure? Why would you ever want to go through this nonsense? A large % of the people whining about this are going to trade in or sell their Tundra before it hits 125k miles. If you are Really worried just buy a 0 deductible extended warranty, you can get a 7yr/125k mile warranty for $1200! Then you are worry free for your entire ownership of the truck!
