Product Overview

This direct-fit cast aluminum pan replaces the factory Allison 1000 transmission pan on your LBZ Duramax. Internal baffles reduce fluid sloshing and improve heat dissipation for smoother shifts under load.

A precision-machined dovetail groove with O-ring seal eliminates messy gasket sealants. The magnetic drain plug and 1/8in NPT temperature sensor port make servicing and monitoring easier.

Powder coated Gunmetal Gray and backed by the Mishimoto Lifetime Warranty.
