2020-2024 GM 2500HD/3500HD 6.6L L5P Duramax Transmission Pans

The factory transmission pan equipped on your 2020-2024 GM 6.6L Duramax L5P doesn't have the largest fluid capacity, which can hinder proper heat dissipation and affect overall transmission performance. Upgrading to an aftermarket transmission pan offers more fluid capacity, cooling fins, and other features that improve cooling efficiency and extend the life of your transmission. These transmission pans are specifically designed to keep your transmission temperatures in check, even when you're out pushing things to the limit.
