2019-2026 GM 8L45/8L80/8L90 PPE Deep Transmission Pan (128051800)
Low and inconsistent fluid pressure — a direct result of rising fluid temps — is behind many GM 8-speed shift complaints. This cast aluminum deep pan increases capacity and uses external fins to actively reduce fluid temps, keeping viscosity up and pressure consistent under load. The magnetic drain plug helps catch wear debris before the next service interval.
- Premium A356.0-T6 heat-treated cast aluminum alloy - a high-strength, thermally conductive material
- Precision-cast using permanent steel molds for a smooth, consistent finish and high dimensional accuracy
- Increases fluid capacity by 3.9 quarts for higher thermal capacity
- Tall 3/4-inch external fins improve heat dissipation, lower transmission fluid temperature, and increase impact resistance
- Deep 7/8-inch internal baffles enhance heat absorption and minimize fluid sloshing
- External fins and internal baffles work together to form an ultra-strong Cross-Bracing structure
- Cast-in gussets for additional transmission housing flange support and increased rigidity
- 304 Stainless steel service plugs with built-in high temperature rated neodymium magnet and Viton O-ring
- Included standpipe ensures accurate fluid level checks during the filling process
- Equipped with a 1/8-inch NPT port with pre-installed NPT plug
