5.7L Transmission Cooler Kits

I keep mine in a ziploc inside of an oil pan, inside of a plastic bag lol. Also learned my lesson to not try to clean them. Just purge with what ever fluid I'm using next.

 

No, sir. We have it listed as a "tool required" to complete the install.

 

Late night, I though he meant like a main pump for the car's tranmission lol

 

Yeah, as mentioned, separately provided. Not sure why I thought of it last night while I was half asleep.

 

What a pia bolt lol. Definitely helps to have various types of 13mm wrenches. Swivel ratcheting wrench did great on the rear. Used like three different types on the front one. Fully tighten it with a short regular 13mm wrench. Couldn't really get anything else to bite

 

Yep. Those two bolts were a bit tricky.

 

Got ‘er installed

I tow a small 17’ boat, nothing too heavy, planning on keeping this tundra for a very long time, so I’m looking forward to many miles and years of a happy cool transmission

 

Has anyone installed the Stillen intake that has the front air intake part? It replaces that plastic part that we cut the two holes in for the coolant lines. So I'm wondering how these two will mesh? I bought the Stillen from a forum member after installing the cooler. I'm hoping it's not too much trouble to get the two working together correctly

I have a 2020 with both the Genuine Cooling kit and the Stillen. My original deflector was already cut up to accommodate the S/C intercooler pump and the transmission cooler lines so I just traced the opening for the Stillen duct. I used a rotary tool, tin snips and file to shape the opening.

 

Great question. Stillen provides you with a new shroud with an opening for the hoses. Instead of drilling the two holes for the hoses, both hoses will pass through the one hole in the Stillen shroud. If abrasion is a concern, I can send you some spiral hose protection just in case, just put it in the order notes if you do place an order.

They'd just pass through this notch, wouldn't they?

 

That is correct.

 

My original deflector was already modified before installing the Stillen.

I did look at installing the Stillen deflector but I suspect it would only allow one transcooler hose through without creating a restriction and I would still have to butcher it to allow for the intercooler pump hoses to pass through.

 

I think @2020Platinum has a youtube install vid and he had the same intake.

 

He drilled holes in the Stillen air deflector:

 

Hey, thanks y'all! Awesome replies! I'll post up my experience with it as well after it arrives later this week.

 

Thanks for the mentions guys!…Scott if ya need help or have any questions shoot me a message…glad to try to assist if I can, and I do have YouTube videos on installing Nick’s kit as well as installing the Stillen…very easy projects and Nick puts together an awesome kit!

 

I didn't want to uninstall the trans cooler hoses so I just cut a hole in the factory shroud for the stillen air inlet. Easy peasy

 

May need to get busy designing a 2022+ transmission cooler kit.

guessing that will be a lot harder to come up with since the current ones use factory OEM hardlines, and guessing those aren't gonna work on 22+. Gonna have to do the whole thing from scratch

 

Did Toyota lower the high transmission temp alert to 260 degrees for the 2020’s? Everywhere I read I see 302 degrees. But yesterday mine went off at 260.

 

That’s interesting… Toyota must have programmed it to set off at 260F in their latest ECU version.

 

Was that the pan or torque converter?

 

TBH I’m not sure. That headunit only has one transmission option. I was just assuming it was the pan. I’ll see if I can find out.

 

Just ordered your kit yesterday though.

 

If you're using a Maestro iDatalink, that's definitely pan temp.

 

Oh gotcha, ya I’m using maestro.

 

If that is your pan , your torque converter is the one that most likely hit the 302 mark which triggered the alarm , I would look into the option of displaying your tc as well

 

Best way to go , you won’t have to worry about temps anymore

 

Last wkend we went exploring in the hills. A couple miles of slowly driving up this hill in 4HI had the pan at 220°F. Certainly glad I had the cooler!
