LPD47391 Low Pressure Drop 40k Transmission Oil Cooler Compatible with Tru Cool Heavy Duty 40,000 GVW Max Trans Cooler with Mounting Hardware (Black)

Works great so far, it is large and may not fit smaller vehicles but was easy to install on my 03 Chevy avalanche and keeps the transmission under 160* even when towing. I did bypass the radiator built in heat exchanger as I live in the south and do not need a trans heater.

03 Silverado 6.0 gas 4l80. Like most of these trucks, when towing the trans temps creep up higher than I’d like. It would sit a little above 210 depending on ambient temperature. On really hot days it would get up to 250/260. I tried some off the shelf trans coolers and didn’t really notice a change. I bought this bad boy and put 2, 7in fans on the front of it and it sat at about 150 degree while moving. It’s a colder day so we’ll see how it acts in summer but Definitely a great improvement! Only thing i didn’t like is that the fins are very easily bent. Just the slightly touch would bend them. Still, 10/10 would recommend

This kit deserves zero stars for including absolute garbage hose. After only four months of use the hose split and dumped several quarts of fluid, nearly costing me a $3,000 transmission rebuild. Not only was there a break (pictured) but while removing the internal webbing was all red, indicating whatever sub par gunk the hose is made from was breaking down completely. If you're here, you dont want to pay for the name brand cooler. The heat exchanger itself does work well but do yourself a favor and throw away the hose immediately, purchase a length of correct SAE J1532 rated transmission cooler line. This could have been much worse had I been towing or far from home all due to a cheap 3/8 hose.

The install was a breeze and the cooler functions properly. Seeing reviews. I personally would get better line and clamps. Evil energy 3/8 s j1532 rated line. And get stainless band clamps for 3/8 s line. All on Amazon. Using those products and this cooler. I eliminated the heater that comes from the radiator then to this cooler (it's there for when it's below freezing to help get to op temp). Cut the lines back where they meet in a plastic clip. Use a circle pipe cutter. Double band clamp them. push the rubber line 4- 5 inches over the existing metal line and clamp there, with two. Then run your lines to the cooler. In the above photo. Connect the purple line on the radiator-To the yellow connection on the cooler. To bypass the heater. SIGNIFICANTLY REDUCED TEMPS THIS WAY. And peace of mind for not loosing fluid and whipping a transmission.

Cooler is fantastic. Hose not so much. Hose is cheap and will rupture quickly. Buy yourself some good trans cooler Hose and its rock solid.

Very large, very nice.

its not good at all the lines are made cheap and will burst ,two times i had to get a new transmission due to this cheap china made BS !! ,i even ordered 300 psi transmission line and bammm again it burst and all mt trans fluid came out and blew my transmission....so i ordered a whole new set up and this time the cooler it self started leaking from the seams.so i had enough and got a whole new one .(ZHSYMX British Radiator oil cooler with AN6 fittings .All this was on my 2008 chevy Silverado 5.3
