Works great

Everything came packaged very nicely. Everything installed super easy. Haven’t seen a considerable drop in temps tho. Maybe 10 degrees but it does take a lot longer to reach them. Here in the dead of summer in Arizona I was seeing 200+ degrees just driving around town and not towing anything (LMM duramax) after install it’s about 180-190 degrees. Overall still happy with it. Be aware that the extended filter does hang down below the transmission pan by about an inch so if you do any off-roading there is a possibility it can get hit. Very nice kit and glad I purchased it.

Worked great

The deep sump with the filters and filter lock worked great, nice to have the extra cooling capacity with the extra amount of fluid.

Good customer service

The customer service was amazing, but unfortunately I needed it due to one of my gallons of trans fluid being cracked. Likely happened in shipping. Everything else came intact and packaged well.
