The Mishimoto Cast Aluminum Transmission Pan fits the 2015-2019 GMC Sierra 3500HD 6.6L Duramax with Allison A1000 and adds 6.1 quarts of ATF capacity for cooler, more consistent transmission performance.
Product Overview
This direct-fit cast-aluminum pan replaces the factory stamped-steel pan on the Allison A1000 behind the 6.6L Duramax. Internal baffles reduce fluid sloshing and improve heat dissipation under load.
A precision-machined dovetail groove with an O-ring seal eliminates messy gasket sealants. A magnetic drain plug and 1/8in NPT temperature sensor port make service and monitoring straightforward.
Finished in Gunmetal Gray powder coat with bottom cooling ribs for a clean underside look.
