Product Description
The BD DIESEL 1061650 Deep Sump Allison 1000 Transmission Pan is the go-to upgrade for 2001–2018 Chevy Silverado / GMC Sierra 2500HD & 3500HD Duramax trucks equipped with the Allison 1000. High volumes of cool transmission fluid equate to long transmission life — and this deep sump pan increases capacity while improving cooling with cast-aluminum heat-dissipating fins.
Built from rugged 356T6 cast aluminum, this deep sump pan adds 3.5 quarts over stock and increases rigidity to help prevent case twisting under heavy load. It includes a magnetic drain plug, a temperature sending unit port, and comes as a complete kit with gasket, deep pan filter, and installation hardware — making it a clean, reliable upgrade for towing, daily driving, and hard-working trucks.
