About Installation

It is important to figure out how much space you have to mount it.

Based on its size, the most common area to install the cooler is in front of the radiator. This will provide the most air flow while driving, which will keep temps low.

Most trucks and SUVs have supports that hold the hood latch or stock trans cooler in place. This would be the perfect place to mount the cooler.

Ready to Install

I normally run the name brand true cool which is pretty expensive these days. So I figured I would try my luck with this knock off and it did not disappoint. It cool just as good as the name brand, plus I like that it's already painted black. I would not use the hose it comes with though. Very good for the price

UPDATE: It's imperative not to use the cooler hose provided with this product due to its extremely poor quality. There's a significant risk of ruptures, potentially leading to transmission damage, accidents, or even fires.In terms of fit and finish, this product falls short compared to the TruCool brand. Although the crucial aspect of leakage is yet to be fully determined, I've installed six of these so far. While they held up to 250 psi on tests, they feel and look cheaper compared to the TruCool brand, despite being only a third of the price.Regarding cooling performance, it's comparable to the TruCool 40k. During testing, the TruCool managed to keep the 4l80 at 150 degrees, while this product hovered close at 165 degrees. While not as efficient as the TruCool, it still represents a significant improvement over factory cooling systems.

I like the cooler itself and it works great. However, the hose and the clamps are such low quality that they had to be replaced within two months. The hose became saturated and busted on both lines. The hose clamps will not tighten up except a little bit and then they pop off. My advice is to use the cooler and buy real transmission cooler line, and better clamps.

Keeps my temps down! It’s very reliable and easy to install, I’ve had it on the truck for about 2 months now and I love it!

Really nice unit. Haven't pulled my trailer yet, but my Temps seem to be about 60 degrees lower without it. Running 120 down from 180+. Super fast shipping.--------------------------------------------------------------------------------------------------------------------------UPDATE!!!My unit sprung a leak on Feb 20. Amazon didn't know how to process a return or refund to honor the lifetime warranty. Amazon did step up after a lot of conversation. Im scared to try another unit after reading a couple of reviews commenting on the quality. It would be horrible to loose my newly rebuilt transmission because of this cooler... Buyer B ware!!!
