Number of Bolts: 17

This PML pan fits GM and Chevrolet 1996 and older vehicles with the 4L80E and 4L85E transmission. PML also makes a deeper pan with more capacity for these applications. See part number 9167 for information on that pan.

This pan can be used on 1997 and newer vehicles if there is enough clearance between frame cross member and stock pan. Most 1997 and newer vehicles do not have enough clearance and need thelate model pan. Part number 9437 provides clearance for the exhaust but will not clear the transmission internals on the early models.

This pan can fit on 1993 to 1996 H1 Hummers, but the frame cross member is very close and you will need to check the drain plug location. On a previous revision of this pan, the drain plug was on the bottom, which required a hole to be cut in the frame cross member to allow the pan to drain. The drain plug is now on the side and may be easier to access.

Image at right shows the rear and driver's side of the pan.

The drain hole is on the driver's side of the pan. All pans include a magnetic drain plug along with the mounting bolts.

On the passenger's side, the pan has a boss that can be machined for a temperature sensor. This is an option and costs $40 per hole. This must be ordered over the phone. Please specify the thread size. PML can drill and tap the boss on the passenger's side between a 1/8 NPT and 1/2 NPT.

Jaguar XJS models with the 4L80 transmission have a stock pan specific to the Jaguar. PML does not make a replacement pan for the Jaguar XJS 4L80 stock pan.
