Let customers speak for us
from 52 reviewsThis is a great product. Most of the parts are OEM, which is why I purchased this kit. Has lowered my transmission temperature by about 25 degrees. Definitely recommend
Installed in my 2019 because I wasn’t comfortable with not having an external cooler for towing our camper. I had the Toyota dealership near me do the install and they were awesome. Highly recommend this kit!
Worth every penny. My brothers 2019 Tundra is carrying a lot of weight from the lift, armor, front bumper, 35” tires. His transmission temps were always between 220-240 degrees F. Now the temps average between 170-190 degrees F. The kit took us about 4 hours to install. It was straight forward, but we took our time. This is a high quality kit and a good investment to protect the transmission.
Install took some time, but was not overly complicated. Looks great, and keeps my temps down.
Had a local shop install the transmission cooler kit. They said it was a very well put together and well built kit. They were thoroughly impressed with the quality of the kit and how easy it was to install. I would recommend this kit to anybody with a Toyota that didn’t come with a factory installed transmission cooler kit.
the kit has good quality and its easy to install
I have a 2019 Tundra pro.
I had the dealer install it. They told me it was a really nice kit . Now I feel mutch more comfortable towing with my tundra.
Don't Heasatate to buy this kit , you will not be disappointed. Also any questions or problems they get back to you right away .
You will not go wrong !!!!
Great cooler does exactly what it’s supposed to my transmission didn’t go over 190 degrees since I installed it
an absolute must if you are towing regularly, on your 19-21 Tundra. I cannot understand why Toyota deleted the Trans oil-cooler for these years. Nothing mechanical changed and the result is much higher temps on a consistent basis. I tow 8400 lb. trailer 60% of the miles on my 2021. This system shaves 20 to 30 degrees off the fluid temp, compared to the stock configuration. This kit uses stock parts, from previous 18 and older Gen 2 Tundras. Very Quality System. Absolutely recommended.
Very satisfied with the cooler. Most components are OEM toyota and the parts that are aftermarket exceed my expectations. Overall a very good kit if you do not have the factory transmission cooler. Transmission temperatures very rarely go over 200 degrees and when they do, they come down rapidly after a heavy tow up a grade. Before cooler my fluid was reaching 250 plus.. That will break down the fluid and if not changed frequently and will shorten the life of the transmission.
Kit was complete and well packaged for shipment. Installed in about two hours, taking my time. I elected to install an inline magna fine filter, and pin my thermostat open. Works great, and keeps everything cool.
bought this product just over a year ago. Works as promised. Temps stays under 200 not over 200 before the kit. No issues. Had a transmission shop put it in. Only thing but doesn't affect the performance is that it doesn't sit straight up and down, it is on a slight angle. Apparently the place where you mount it doesn't line up. They spent at least 2 hours and it was either go with the slight angle or drill unnecessarily into the truck. The owner said it won't affect performance. So far no complications with that. So I wouldn't let this discourage anyone planning to buy. Its worth the investment. Even the mechanics said this was a good thing to invest in.
Just finished my first trip towing my travel trailer since installing the kit. Torque and pan temps
stayed within a few degrees of each other the entire trip. I am so glad I don’t have to worry about the trans temps anymore. Thanks for making this kit.
Works great and keeps the tranny temp down.
3 years ago I installed the kit. As with most the hardest part of the install is the hard lines that go along the engine. Patience is key. After that everything is a piece of cake for anyone with average mechanical skills. No leaks or any problems since the install. Temperature drops of 20-30 degrees are a result. I feel that even if you don’t tow, get the cooler.
