PML designed this transmission pan for GMC and Chevrolet 1990 to 1996 model year trucks and SUVs with the 4L80E and 4L85E transmission.

Benefits:

Extra capacity, 3 3/4 quarts over stock
Drain hole and magnetic drain plug for easy fluid changes
Finned for cooling
Heavy duty sand cast aluminum construction
Machined flat gasket sealing surface
Can optionally be machined for a temperture sending unit

Applications:

Typically, these vehicles have a 4L80E or 4L85E transmission and can use this PML transmission pan:

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

Vehicle configurations vary. Always verify your transmission and clearance.

Many 1997 and newer vehicles have the frame cross member running under the rear of the stock pan and do not have enough clearance for this pan. See PML Part Number 9437 for a transmission pan that clears the frame. However, PML Part Number 9437 will not clear the transmission internals on 1990 to 1996 transmissions.

PML also makes a less deep pan for trucks with skid plates or cars. It is PML Part Number 9313.

Filter

There are two different filters for the 4L80. PML recommends the Early Model filter for this transmission pan. Example part numbers are:

GM OEM part number 08684221
Pioneer Filter Part Number 746052
Wix 58917

A filter extension is not needed since the PML pan has filter supports to hold the filter in place.

If using a late model filter, the supports in the PML pan are not designed to rest on the bumps on the bottom of the filter. PML does not recommend using a late model filter.

The installer must verify fitment and installation. Be sure to check that the filter sits correctly.

Gasket

PML recommends a cork or cork composite gasket with our GM 4L80, 4L80E transmission pans. For example, Mahle Part Number W39379. This gasket is about 0.070 inches thick. Many other manufacturers also make cork/cork composite gaskets for the 4L80 transmission that would work great with this PML transmission pan. This is just an example.

Optional Temperature Sending Unit Machining

Optionally, this pan can be machined for a temperature sending unit. This would be for an aftermarket temperature gage. There is boss on both the driver and the passenger sides of the pan for this.

If you would like PML to drill and tap the hole, there is a custom machining charge. Select the option before adding pan to cart. A plug for the hole is included.

The standard size is 1/8 NPT. Call or email if you need a different size.
