2001-2004 GM 2500HD/3500HD 6.6L LB7 Duramax Transmission Pans, Filters & Fluid

One of the key drawbacks of the 2001-2004 GM 6.6L Duramax is the limited fluid capacity of the stock transmission pan, which hampers heat dissipation and overall transmission performance. Our selection of transmission pans is precision-engineered to increase fluid capacity and feature cooling fins for improved cooling efficiency. The added fluid capacity helps dissipate heat more effectively, even during heavy towing or hauling. Additionally, we offer premium filters and transmission fluid to ensure long-term reliability and optimal performance.
