Description Technical Specs

This PML pan fits GM and Chevrolet 1997 and newer trucks, SUVs, and vans with the 4L80E and 4L85E transmission. It also fits the Hummer H1. Some examples of vehicles that this pan will fit are:

  • Hummer H1, 1997-2005 with 5.7, 6.5 diesel engines
  • C2500 1997-1999 with 454, 6.5 diesel engines

  • Savana, 1997 and newer, 6.0, 6.5 & Duramax diesel engines

Some models of Sierra and Silverado can use this pan but may require modification of the heat shield. Please check carefully for clearance for a deeper pan.

Earlier model vehicles will need a pan without a slant to avoid interference with transmission internals. See this extra capacity PML pan for GM 4L80E/4L85E transmissions on early model trucks.

The pan has a boss that can be machined for a temperature sensor.
