Dimensions: Click here for dimensions.

Number of Bolts: 17

PML designed this pan for vehicles with 4L80E, 4L85E transmission and needing a space saving, high quality pan.

Benefits:

1 1/2 quarts of extra capacity over the stock pan
Less than 1 inch larger than the stock pan
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
The distance from the flange surface to the inside bottom of the pan is approximately 2.75 inches. This is the same as the stock pan so the bottom of the pan supports the filter. Custom filter or supports not needed.

Applications

Typical Applications:

Muscle cars such as Camaros, Chevelles
1993 to 1996 Hummer H1 (see note)
Custom hot rods
Trucks with skid plates
Vans

Always verify your transmission and clearance. Vehicle configurations vary.

Many 1997 and newer vehicles have the frame cross member or exhaust 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 or exhaust.

PML also makes a 4L80E, 4L85E pan that is 3 3/4 quarts over stock. It is Part Number 9167.

Note for Hummer H1: This pan can fit on 1993 to 1996 H1 Hummers, but the frame cross member is very close. Check your Hummer to verify the clearance.

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.

On the passenger's side, the pan has a location that can be machined for an aftermarket temperature sending unit.

If you would like PML to drill and tap a boss, there is a machining charge. A plug for the hole is included. The standard size is 1/8 NPT. If another size is needed, please call or email.

A filter extension is not needed.

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.
