When the mainline pressure is increased with upgrades such as a high-performance transmission kit, your transmission generates additional heat. A PPE 6.6L Duramax Performance Transmission Cooler is critical in such situations.

2004.5 LLY Duramax 2500HD Trans Fluid Cooler

The fitment to the vehicle mounts was excellent thanks to the pivoting arms of the lower 2 piece mount set up that came along in the cooler kit. The trucks aluminum cooling lines needed a little bending to get proper insertion alignment into the cooler itself but it was not an issue for a shade tree mechanic. Trans fluid temps dropped 25 to 30 degrees depending on the speed and type of driving. Nicely done PPE.
