We designed and manufactured this 10L1000 Allison transmission pan for 2020 and newer Duramax trucks. The design keeps the general shape of the OEM pan while adding extra capacity and a finned bottom for heat dissipation.

Benefits of Pan Design

• Extra capacity
• Finned to increase surface area for heat dissipation
• Drain with magnetic drain plug
• Thick walls and gasket flange
• Heavy duty construction
• Shape similar to the OEM pan to replicate its fluid flow and dynamics
• Deep sump middle design avoids clearance issues with cross frame members and exhaust packages
