5.7L Transmission Cooler Kits

Good to know! I’ll add that to the list of compatible superchargers.

 

Got to really work my truck today. Towed up a steep 3 mile long windy road with a top speed of 25 MPH and then had to back my trailer into a tight spot. Pan temps hit 225 and torque converter hit 275 backing the trailer. I don’t think it would be possible to back the trailer like I did without a cooler as the transmission would have certainly overheated. Very happy.

 

Interesting
Thanks for the testimonial

That sounds pretty hot

Which cooler do you have, and what are you using to monitor temps?

 

I have the MHX-514 and use an ODB Link MX+. Normal highway temps are 190-195 but that’s with the torque converter locked. 225 is definitely fine for short durations. I was seeing 225 pan and 250+ torque converter temps in the city unloaded before I installed the cooler.

 

Do you still have some brackets for MHX-514 in stock?
I would like to order one

 

I might be interested also if they are still available.
How much of a difference is there between the Setrab 15 and the MHX 514?

 

Towed an Atv on my 6 1/2 x 12 trailer yesterday through north western pa. Probably 2000 lbs total. Lots of steep climbs and lots of lake effect snow squalls. Maybe a total of a 180 miles. Mostly 45 to 60 mph. Pan never got over 190 degrees. Today unloaded with mixed driving pan stayed about 180 degrees. Outside temps over the two day where between 28 and 42 degrees. Very happy with the cooler install.

 

@tiogajoe if you get a chance, could you snap a picture or take a measurement?

 

Unfortunately, I don’t. I only offer the Setrab 15-Row cooler for the 19-21 Tundras. You won’t be disappointed with the quality or performance of the Setrab.

 

I can assure you that the Setrab-15 Row cooler is no compromise in performance or quality. If you were to have the same truck with the same load I’m not sure you’ll see much of a difference in pan temperatures. This is because the thermostat only allows ATF to flow to the oil cooler past 185-190 degrees and both coolers will maintain a pan temp of 190-220 under the same load. The Setrab-15 Row cooler is also larger than any factory designed transmission cooler Toyota has put on a Tundra.

 

Isn't a better way to check level by putting the leveler on the underside of the transmission pan? As opposed to frame or anywhere else.

 

I was thinking the same thing when installing. Heres the conclusion I came to:

Since we are looking for a trickle from the level check stand pipe, not a drip, as long as the truck is level (front-back, side-side) the oil level will be close enough. Even if the level bubble is not perfectly centered but still within the level marks it should be fine. Again, all because what we’re looking for before installing the drain plug is a trickle, not a full stop of out flow. The small variance from perfect level shouldn’t matter.

Thoughts ??

 

I use the frame when doing the level check procedure. Toyota specifies the truck must be within 1 degree of being level from front to rear/side to side.

 

The shop floor at the dealership is most likely level already. The reason I include it in my instructions is because most house garages and/or driveways have a slant or grade to them to divert water.

 

That’s correct.

 

I just check the Toyota shop service manual (TIS 2016-2021 Tundra). In the automatic transmission fluid adjustment section it states: “Maintain the vehicle in a horizontal position while adjusting the fluid level”. In the automatic transmission fluid replacement section it states: “Set the vehicle on a lift so that the vehicle is kept level when it is lifted up (make sure that tilt angle from front to rear of the vehicle is within +/- 1 degree”).

 

That is correct , my garage is 3 inch higher in the back .
Usually I backup the truck into the garage and was not level and needed front to be raised .
All I had to do is to get The truck forward so the front of it is in the back of the garage and that sucker was 100% level front to back and side to side

 

I'm debating if if should change my fluid since installing my cooler at 16820 miles. I did some towing of our mini camper (2600lbs) several times before installing the cooler kit. I kinda thought my fluid looked pretty good? I thought about maybe doing a drop and fill at 25,000 miles and once a year after that point. Any thoughts?

 

I was towing 4200 lb trailer for the last 3 years in the summer time that is . I have 15k on my truck now and the oil looked pretty good to me .
Will do the service on the 60k recommended interval

Question on the MHX-514 cooler. Does it make a difference which of the two ports is on top? For instance, the cooler has a metal tag on one side and a black model label on the other side.

 

I concur, after I installed the MHX kit , and leveled the truck and added/drained ATF fluid , I started noticing smoother and more positive shifts than the past year or so I had the truck !!!

 

The MHX-514 cooler is bi-directional so you may install it either way.

 

Thank you brother!

 

Whoops! I meant bi-directional. I edited my last post.

 

For those who have a kit installed… I started a Facebook page (Genuine Cooling Systems). If you guys wouldn’t mind dropping a picture or two of your Tundras with the kit installed and a short review I would greatly appropriate it.

Thank you!

 

Have you found someone to do a video for you yet? I would be interested.

 

I have. He is currently in the works of developing the install video.

 

I set up the fusion app to monitor. I have not done the custom PID from the first page of this thread. The app does have A/T oil temp #1, and number 2 as a selectable temperature to monitor. Is that the pan and converter?

 

First usually the pan and 2 converter

 

#1 pan, #2 torque converter
