Pretty much fit just a little bend of some hoses. Took it for a 800 mile week drive and temp never went above 188. Before it was over 210. Great product and highly recommend

Super quality, installed great, and works absolutely perfect.
Temps are at 190°F in the pan and temp at torque converter hasn’t surpassed 230°F
Also, did a flush, pan filter change, and filled everything with AMSOIL signature series just to be safe.
I tow a 3500lbs. GVWR camper all over the mountains of Montana in a 2019 Tundra and I guarantee I would be breaking 240°F consistently if it were not for this upgrade. It’s wild to me that Toyota removed this from the 2019-2021’s.
Don’t even hesitate, it’s spendy but so so worth it!

The Genuine Cooling Systems transmission cooler was highly recommended by my transmission shop. I've been very happy with the results. I tow a 6,000 lb trailer and with this unit installed, I rarely see pan temps higher than 185 degrees, whether towing or not. I have not yet towed in the mountains, but I am confident that I won't run into any trans overheating issues.
Also, it was very thoughtful that the manufacturer included (at no additional charge) and ODB-II scan tool so I can easily monitor the trans fluid temps.

Install was fairly easy. Dropped my pan temps a good 20 tp 25* pulling my bass boat. Highly recommend this add on

I don’t know what the temperature it was prior to installing it, but for what I seen I can get in the 245 ish just driving with no towing. After I added it I can see mine in the 190s and 215 the highest while towing. A must in my opinion.

I have had this on my list for a while and after installation I wish I would have pulled the trigger much earlier. Great quality parts in the kit and the installation is so clean. Functions perfectly and has my transmission fluid operating much cooler.

In addition to the easy installation, I am now getting transmission pan temps in the 185° range in hot Arizona desert heat (100° to 110°). Before the cooler install, I was getting temps as high as 240°. I left the thermostat pinned because it never gets that cold here.

I purchased the 15 row full kit, and I’ve installed it on my 2021 Tundra Trd Pro. It’s great, now I can tow with confidence and worry free.
Thanks to Alkesh who made it easy to acquire the unit.

While I did not install the unit myself, it was installed by my local Toyota dealership . The service representative told me how impressed he and the master mechanics were at the quality and completeness of the Tundra Kit. Going on to say that it was as good and actually better than an all OEM system. I am very pleased with this quality, well thought out product and am confident that it will last the life of my vehicle.

I needed a transmission cooler for my 2022 Sequoia and after a search of the forums, this product was frequently rated the top product. The price is steep, but the kit comes complete with all parts, scanner, and trans oil to complete your project. The fit and detailed instructions (and video) were instrumental to a successful

Wow, this genuine cooling system setup was so straight forward to install, I love it. It was great not having to source all these pieces /parts separately on my own. Now that it is installed I can feel confident my 2021 tundra’s transmission will last a very long time.

I received the kit in perfect condition about 3 weeks ago, but today was the first chance I have had to install it. I had watched the videos several times so installation was quite easy. Hi quality components and everything you need except the tools. I highly recommend one of the video suggestions to put the inlet and outlet hoses on the thermostat before installation. Only had one minor issue - one of the threaded backer plates for the Sertab mounting bracket had a hole that was not threaded. Luckily I had an M6 tap on hand and took care of it. Added 1.5 qts of ATF using a Slippery Pete hand pump. Noticed it took longer to come to temperature than previous drain/fills I had performed. All in all only lost about 1/2 cup of fluid between puck removal and level check. I took it for a run on the highway - pan temperature never got above 186°F. Used to see 205°F on the regular, even without a trailer. The big test will be later this fall, towing a 5000 lb travel trailer to the Blue Ridge Parkway. I wish I had this earlier this summer during a trip from NC to Yellowstone! Crossing the Bighorn Mountains in Wyoming is what convinced me I needed this.

Before installing this kit my truck's transmission was reporting temperatures around 260-290 F. After installing the kit it now reports temps below 200F. Simply amazing!!!

I love that the kit has everything that you need so you’re not tracking down parts or trying to figure out what works with what. I haven’t gotten to tow with this kit yet but prior to install I was seeing temps up as high as 240. Since the install I have yet to see 200.

The instructions and YouTube videos made this very straightforward and fun. My transmission temps have lowered some.. The converter temp reading reaches upwards of 220-225 but the pan temp usually holds around 195-200. These temps are about 20-25 degrees cooler since installing the kit.
