Before my trans temp was getting up to 220 with bigger tires and no towing . Now I’m staying I’m not getting above 175 . Seems like my truck runs smoother too when punching it !! Highly recommended. Got it installed by a pro for $250 can’t beat that

Great quality transmission cooler kit! I am so impressed by the packaging. OEM lines, fluid and clamps with a really high quality aftermarket cooler. The install took me about 4 hours. I highly recommend this kit. If you have average mechanical skills like me, just save the money and install it yourself. Watch the videos and you will be just fine. Thanks for a great kit I appreciate it.

Intsalled this on my 2021 1794 Tundra. Installation went as expected

. No hickups.

Very well made kit. I would purchase again if I need it on another Tundra. Install instructions are very good. I have not towed with it yet but I'm looking forward to it. When daily driving the cooler brings the temp down very quickly as soon as you're over 200 degrees.

Second time purchasing one of these kits, has everything you need.

Great product and company to work with. This is the only kit you should purchase.

Works great, fits great.

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
