This is a must upgrade since many tundra’s and sequoias din not come with one from the factory. We use our TRD sport Sequoia for family vacations and my wife’s daily driver as she shuttles the kiddos around town. With 35” wheels an ARB bumper and other upgrades I wanted an external cooler for the transmission. Genuine cooling systems made it possible. With a larger 15 row Setrab cooler and custom bracket and factory hardware. It’s an no brainer to purchase there unit. I am very satisfied with the kit I have recommended it to all without one.

We just ordered and installed this kit on a customers 19 Tundra. Everything was labeled well, instructions were very clear, quality of parts is top tier. I really like that it used OEM Toyota Parts.

I was hesitant, considered sourcing the parts myself. ultimately i realized my time is worth more, so spending the money on this product turned out to be the best option. everything works as advertised. Definitely a high quality product and very simple to install

Driving same 3 hour moutain route before and after kit gave 15-40f deltas. (With trans thermostat pinned open.)

Tundra torque converter just locks in heat by design. Red lights, slow crawls, and third gear towing just cause heat spikes. This does not change that but gives you a lot more headroom before your fluid starts burning.

260f+ towing spikes. 245 red lights. And 8k miles after a flush the trans fluid was very dark again was enough to convince me to pay for kit. Worth every penny.

Toyota dealer and local shop both quoted me 2-3 hours for job. 500$ for professional install in 2024.

Excellent packaging, simple process to install.

Transmission temp now staying below 200F while commuting over mountain passes.

The parts I received from Genuine cooling
Systems was complete. Since being installed on my 2020 tundra it keeps the
Truck operating 12 degrees cooler.
Thanks for a great product.

Watched the YouTube video of the install and just followed along. Time consuming but everything fit perfectly.

Great kit

This 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 !!!!
