First of all super fast shipping and packaged great to protect the fins. Everything lined up and bolted in just fine will definitely be returning here to order another one for my other truck as well.

This transmission cooler was an easy direct fit install! The connectors fit way better than stock and you don’t have to worry about breaking them because they’re stronger than stock too. My trans even runs about 25 degrees cooler than stock! That’s because it has an extra layer of cooling as compared to stock! I’ve ordered a few other things from XDP before and have had zero problems, I will definitely be using them for anything and everything I need for my truck from here on out! Order #1520468

Installed on 2005 LLY. I ordered it factory transmission lines for a LBZ/LMM then mounted with room for future oil cooler. Couldn’t be happier with the build quality of the cooler. Temps take much longer to climb and rarely get to 200 unless a long trip or hauling. Order Number: 2156332 Website Order Number: 1512568
