2017-2019 GM Duramax 6.6L L5P Transmission Pans, Filters & Fluid

The factory transmission pan on your 2017-2019 GM 6.6L Duramax L5P is quite small in fluid capacity, leaving a lot to be desired when it comes to proper heat dissipation and functionality of your transmission. Aftermarket transmission pans for your 2500 or 3500 GM Heavy-Duty truck come equipped with larger oil capacities, cooling fins, and other features you truck's manufacturer overlooked to keep your transmission temps under control in every situation. The main benefit is the upgraded fluid capacity that delivers impressive heat dissipation even when towing or hauling heavy loads. GM Duramax Fitments: 2017, 2018, 2019 GM 6.6L Duramax.
