2019 5.7 trans cooler location

I've read most of this thread. I am still a little confused if you can add the transmission cooler to the 2019? Please chime in if possible. I'd rather pay a few hundred dollars then sacrifice reliability.

 

No one knows 100% cause I don’t think anyone has done it, but it appears there is just a spacer you’ll have to switch out for the trans thermostat. Should be same trans and same holes since 07. Then run the lines and get a cooler.

 

I don't have much to contribute but holy crap I read through every single post in this thread. I give myself a round of applause for it.

 

What is everyone using to monitor transmission temps?

 

Wouldn’t this fall into a lawsuit since our window stickers show Eng/Trans coolers and there’s no trans cooler being sold that we should either get a discounted rebate back to us or a dealer installed trans cooler. This would make sense, since I bought my truck thinking it had a trans cooler on it. So, I was sold a false bill of goods that had poor representation listed on the mfg window sticker!

 

I’m wondering how the window sticker says it has a cooler but they removed it I’m not happy about that part at all

 

Not my exact truck but a window sticker showing Eng/tans coolers “plural”

 

What's going to tick me off is when they add the cooler back to the tundra in 2021 model year.

 

I use a BD tuner. Some use a scangauge. Some use an OBD Bluetooth thing to their cell phone app.

 

I would want something that I can use on my phone. Any recommendations?

 

I’ve never used a phone app but there are a lot on Amazon. Probably mostly Chinese made but maybe someone else on here has experience with one.

 

I use iPhone app OBD Fusion. You can buy an add on for ~$10 that has ATF temp codes preinstalled so no messing with PID's

Coupled with Foseal Improved Version Car WiFi OBD2 Scanner for $20 from Amazon I get all I need. The Foseal is just a branded version of an OBD. If you see similar for cheaper I'd grab it!

I almost went with one of the "nicer" blue tooth ones but read fine print as many dont support ATF temps under any circumstances.

 

Thanks for that but it clearly says in the article:

"The vehicle manufacturer looks at all the data and decides what towing limits to place on that particular make/model vehicle."

Word on the street is Toyota has always been more conservative than rival brands..... Just like the floor mat issue they KNOW if catastrophic failures result in deaths it's better to point at a spec that was exceeded.

 

Well we could go round and round about this; certain vehicles behave differently under different circumstances and can't all be subjected to the same tests. Take the front impact crash test where Tundra basically fails BUT notice they are ramming it into a sharp immovable object like I have yet to see in normal driving.

Manufacturers are free to rate lower which I think Toyota does. I imagine they could rate closer to max if they preferred.

I think Toyota only rates the Tundra payload ~100lbs more than Tacoma which is patently ridiculous! My Tacoma was sagging under a load and performance suffering, hence the change to Tundra, I transferred exact load and could not even feel it in the Tundra. Added another several 100lbs and no different in performance or handling....

But my point is there are numerous things that could be done to save the cost of an ATF cooler if profit margin was prime concern. I've never seen a power steering cooler before! Never had a power steering pump fail......Even if would you rather replace a dozen ps pumps or one transmission?

Thanks

 

Yes absolutely speculation!

I argue it's not a big deal but am still fraught with curiosity as to why!

All the rhetoric I've read hear does not satisfy my inquiring mind.

 

There must be something else going on here. If the cooler does not open until 230 degrees why do the 2019+ maintain 20-30 degree average above the previous models?

 

There is not nearly as much heat transfer area in the warmer/cooler as in the old air-to-fluid exchanger, which was additive to the cooling provided by the warmer/cooler. Plus, the cooling medium (engine coolant @ 200 deg) is far less efficient than ambient air at say 100 deg F.

In other words, the warmer/cooler on 2019s has inadequate cooling capacity to keep the transmission fluid at 230 deg using engine coolant as a cooling medium. The fluid temp is going to climb until equilibrium is reached for the operating conditions.

 

When my trans reaches 194 as measured by a BD tuner, the ATF hose coming from the transmission is warm. I believe it opens well under 230.

In my previous 2010 where the grill opened with the hood and I could get to it, the ATF cooler was hot when the trans got to around 200.

 

Leaving your house...forever?

 

looks like he is TAKING his house...lol

 

Wait...what's the date on this thread. I'm posting in a time-warp; feeling deja-veax all over again.

 

Posted this in the other transmission thread but this is more trafficked and I want to get some more opinions on this.

Has anybody thought about adding just a small coolent radiator to the inlet side of the "warmer". I've noticed that the tranny temp mirrors the coolent temp going in pretty closely. It's not as intuitive to check actual coolent temp at the inlet. I measured with ir gun and the coolent was only a few degrees cooler than what the obd2 was reading for trans pan temp

 

I am concerned about screwing with the flow of coolant. I dont want to compromise the motor to maybe help the trans. I dont want to stress the water pump as it is the only thing pushing the water and the small channels in a cooler do add back pressure.

Now I have thought about removing the trans warmer completely from the engine coolant circuit. You can just tie the 2 coolant lines from the motor together effectively bypassing the trans. then run all new lines from the warmer and install a secondary radiator(small, intercooler size with efan) and a electric water pump.
