Pacific Performance Engineering 128051220 Heavy-Duty Deep Cast Aluminum 10L80 Transmission Pan Black - GM SUV

The Pacific Performance Engineering (PPE) 128051220 is a heavy-duty deep cast aluminum transmission pan engineered for GM SUVs equipped with the 10-speed 10L80 automatic transmission. Excessive heat is the number one enemy of transmission longevity — as fluid temperatures rise, viscosity drops, thinning the protective film around internal gears and bearings and accelerating wear. The PPE deep pan directly addresses this by adding 2 extra quarts of fluid capacity, giving your transmission more thermal mass to absorb and dissipate heat under demanding conditions.

Key Features:

• A356.0-T6 Cast Aluminum Construction — High-grade alloy delivers exceptional strength, rigidity, and superior heat transfer compared to stamped steel OEM pans
• 3/4-Inch External Cooling Fins — Maximize heat-wicking surface area to actively dissipate heat into the surrounding airflow, lowering fluid operating temperatures
• 5/8-Inch Internal Baffles — Increase fluid-to-aluminum contact for enhanced heat absorption while minimizing fluid sloshing for consistent fluid pickup
• Cross-Bracing Structure — External fins and internal baffles work in tandem to form an ultra-rigid structure that distributes impact loads and improves pan durability
• CNC Machined Grooves — Increase effective surface area for improved heat dissipation
• Cast-In Gussets — Provide additional transmission housing flange support and increased overall rigidity
• Integrated Fluid Level Check Tube — Sealed with a PPE 1/2-inch stainless steel magnet-equipped plug for convenient fluid monitoring
• Neodymium Magnet Drain Plug — High-power, high-temperature-rated neodymium magnet embedded in a stainless steel drain plug captures harmful ferrous metal particles before they can damage transmission internals; includes Viton O-ring seal
• 1/8-Inch NPT Access Port — Tapped and plugged port accommodates an optional transmission temperature sensor
• Black Finish — Durable black anodized finish for a clean, finished appearance under the vehicle
• Compatible with OEM Gasket — Reuses the factory gasket; no replacement gasket required
• Limited Lifetime Warranty — Backed by PPE's manufacturer warranty

The PPE 128051220 transmission pan is a direct bolt-on upgrade that replaces the factory stamped pan. The increased fluid volume means slower heat buildup, more stable operating temperatures, and better protection during towing, hauling, and performance driving — all critical for extending the service life of the GM 10L80 10-speed transmission.
