The Mishimoto Cast Aluminum Allison 1000 Transmission Pan fits the 2015-2019 Chevy Silverado 2500HD and adds 6.1 quarts of ATF capacity for cooler, more stable transmission temps.
Product Overview
This direct-fit cast aluminum pan replaces the factory stamped steel pan on the Allison 1000 behind the 6.6L Duramax. 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. Pre-installed bolt retainers hold the fasteners in place during install.
A magnetic drain plug captures metallic debris, and a 1/8in NPT port accepts a temperature sensor for easy monitoring.
