The Mishimoto Cast Aluminum Transmission Pan fits the 2007-2014 Chevy Silverado 3500HD with the Allison 1000 and adds 6.1 quarts of ATF capacity for cooler, more stable transmission operation.
Product Overview
This direct-fit pan replaces the factory Allison 1000 stamped steel pan with cast aluminum finished in Gunmetal Gray powder coat. Internal baffles reduce fluid sloshing and improve heat dissipation under load.
A precision-machined dovetail groove and O-ring seal replace the messy flat gasket setup, and pre-installed bolt retainers hold the fasteners during install. A magnetic drain plug and 1/8-inch NPT temp sensor port make service and monitoring straightforward on the 6.6L Duramax.
