This PML pan fits GM and Chevrolet 1996 and older trucks with the 4L80E and 4L85E transmission as well on 1997 and newer trucks with clearance. Some examples of vehicles that this pan will fit are:

  • C2500 1990-1996 with 454, 6.2 & 6.5 diesel engines
  • K2500 1990-1996 with 454, 6.2 & 6.5 diesel engines
  • C3500 1990-1996 with 454, 6.2 & 6.5 diesel engines
  • K3500 1990-1996 with 454, 6.2 & 6.5 diesel engines
  • Suburban 1992-1996 with 5.7, 454, 6.2 & 6.5 diesel engines
  • 1997 and newer vehicles with clearance

This pan can be used on 1997 and newer vehicles when there is enough clearance for this larger pan above the frame cross member. Many 1997 and newer vehicles do not have enough clearance and need the PML late model pan. PML also makes a low profile pan for GM cars with these transmissions.

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

This pan is designed for these early model 4L80E, 4L85E transmissions (about 1990 to 1996). PML's pan for the later model vehicles (part number 9437) provides clearance for the frame but will not clear the transmission internals on the early models.

GM 4L80 filters


Both GM early model and late model 4L80 filters should work with this transmission pan. This PML pan has filter supports to hold the filter in place. A filter extension is not needed.

The installer must verify fitment and installation.

Installation on a 1997 K3500

Mike installed a PML 4L80 transmission pan on his 1997 K3500. He does a lot of towing with his K3500 and wants to keep his fluid cooler during trips. He installed the PML pan and a rear differential cover in 2004. Ten years later the truck still runs great.
