PPE 10L1000 Deep Transmission Pan - GM 6.6L Duramax Allison L5P 2020-2026

PPE Heavy-Duty Cast Aluminum Transmission Pan

Protect your GM 6.6L Duramax 10L1000 transmission from excessive heat with the PPE Heavy-Duty Cast Aluminum Transmission Pan. Engineered from premium A356.0-T6 heat-treated aluminum alloy, this upgraded transmission pan increases fluid capacity by 4 quarts while dramatically improving heat dissipation, structural rigidity, and transmission protection for demanding towing, hauling, and performance applications.

Key Features

• Constructed from premium A356.0-T6 heat-treated cast aluminum alloy
• Precision-cast using permanent steel molds for exceptional strength and dimensional accuracy
• Increases transmission fluid capacity by 4 quarts for improved thermal management
• Tall 3/4-inch external cooling fins maximize heat dissipation and impact resistance
• Deep 1.2-inch internal baffles improve heat transfer and reduce fluid slosh
• Cross-bracing design formed by internal baffles and external fins increases pan rigidity
• Cast-in gussets strengthen the transmission housing flange mounting area
• 304 stainless steel drain and service plugs with high-temperature neodymium magnets
• Integrated standpipe ensures accurate fluid level checks during servicing
• 1/8-inch NPT port with pre-installed plug for temperature sensors or accessories

Benefits

By increasing fluid capacity and improving cooling efficiency, this transmission pan helps maintain proper fluid viscosity and lubrication under heavy loads and elevated temperatures. Integrated magnetic service plugs capture harmful metal particles, while the reinforced cast design improves durability and impact resistance for long-term transmission protection.

Fitment

Fits GM 6.6L Duramax diesel trucks equipped with the 10L1000 10-speed automatic transmission. Compatible with OEM transmission filter and gasket.
