Why upgrade

This Mishimoto Aluminum Transmission Pan is a direct-fit, high-performance upgrade for your 2001-2019 Chevy/GMC 6.6L Duramax. Cast from high-quality aluminum and powder coated Gunmetal Gray, our transmission pan is a robust and long-lasting upgrade for your vehicle's transmission. Mishimoto engineers these kits around real chassis packaging, so hoses, coolers and adapters line up without fabrication on the listed years. Follow the published torque specs and install guide, reuse sensors where instructed, and confirm clearances if you run other supporting mods. Every unit ships with the Mishimoto Lifetime Warranty for as long as you own it.
