The Mishimoto Cast Aluminum Transmission Pan fits the 2001-2006 Chevy Silverado 2500HD with the 6.6L Duramax and Allison 1000 transmission. It adds 6.1 quarts of ATF capacity for cooler, more stable transmission temps.

Install Difficulty: DIY Possible
Bolts to the Allison 1000 transmission with hand tools after draining ATF; typically installs in 60-90 minutes and requires refilling with 6.1 additional quarts of ATF.

Product Overview

This direct-fit pan is cast from aluminum and powder coated Gunmetal Gray. Internal baffles reduce fluid sloshing and improve heat dissipation under load.

A precision-machined dovetail groove holds the O-ring seal in place, replacing the factory flat gasket and messy sealants. Pre-installed bolt retainers keep fasteners in the pan during install.

A magnetic drain plug catches metallic debris, and a 1/8in NPT port accepts a transmission temperature sensor for monitoring.
