Overview

The PPE Heavy-Duty Deep Aluminum Transmission Pan is a direct replacement for GM Allison 1000, 2000, and 2400 series transmissions from 2001-2019. It is constructed from A356.0-T6 heat-treated cast aluminum alloy, providing superior strength and thermal conductivity.

This deep pan design increases fluid capacity by 4 quarts, offering greater thermal capacity and better fluid dilution. It features tall 3/4-inch external fins for improved heat dissipation and deep 1.2-inch internal baffles to enhance heat absorption and minimize sloshing. The pan also includes a 304 stainless steel drain plug with a neodymium magnet and Viton O-ring, 1/8-inch and 1/4-inch NPT ports, and integrated filter supports. A new deep transmission filter is included.

Show original supplier description

Upgrade your GM Allison 1000, 2000, or 2400 series transmission with the PPE Heavy-Duty Cast Aluminum Deep Transmission Pan. This pan is Precision-cast using permanent steel molds from A356.0-T6 heat-treated aluminum, offering superior strength, durability, and thermal conductivity compared to standard stamped-steel pans. The deep design increases transmission fluid capacity by 4.3 quarts, providing greater thermal stamina and reducing the risk of overheating. Its tall 3/4-inch external cooling fins and deep 1.2-inch internal baffles work together to create an ultra-strong cross-bracing structure for enhanced heat dissipation and impact resistance. The pan features cast-in gussets for additional transmission housing flange support and increased rigidity. Included is a 304 stainless-steel drain plug with a high-temperature neodymium magnet to capture ferrous metal shavings, along with a fluid fill fitting and plug for easy servicing. It also comes with integrated filter supports, a new deep transmission filter, and is compatible with the OEM gasket. The pan is available in Raw, Brushed, or Black finishes.
