This PML tranny pan fits many 1989 to 2004 Ford 2WD and 4WD trucks and SUVs with the E4OD or 4R100 transmission. Typical applications are:

  • F250, F350, F450, F550, 1989 to 2002
  • F150 Lightning trucks, 1993 to 2004
  • Some full size Broncos
  • Excursion
  • E250 (5.4 V8), E350, E450 vans and motor homes
  • Lincoln Navigator

Trucks with 5.4 Gas Engine: Check for carefully for clearance from exhaust or frame cross members. Generally, the stock exhaust runs too close to the stock transmission pan to allow for a larger pan.

Excursion owners: Excursions with V10 engines have reported that the exhaust hits near the front of the pan. Excursion owners have told us that our transmission pan will clear the frame cross member. If you have a 4WD, you may need to loosen the rear transmission mount bolts and jack up the transfer case slightly to ease access to the bolts along the back of the pan.

If you have a 460 V8 and a "Banks Power Pack" kit, please check carefully for clearance between the exhaust and the transmission pan. We have had mixed reports from customers.

Because vehicles vary, always check your truck or SUV to verify the configuration and clearance before ordering.

Drain and Temperature Sending Unit Locations

The drain is on the left (driver) side of the pan at the deepest area to allow for complete draining.

Drilling and tapping for use with aftermarket sensors and gages is an option. This pan has two locations that can be machined, one on the driver side and one on the passenger side. These locations can accommodate from 1/8 to 1/2 NPT. PML has a machine shop on site and can machine a pan to your location and thread specifications. There is a $45 machining charge.

First image shows a pan machined with a 1/8 NPT hole for a sending unit on the driver side of the pan. The second image shows the right/passenger side of the pan. The location that can be drilled and tapped is the half circle area near the middle.

When PML drills and taps a hole, a plug is included.

About Filters

PML designed this pan to use the stock filter.

The pick up for the transmission fluid is at the same point with this pan and the stock pan. The fluid level is at the same place with the PML pan as with the stock pan. No filter extension is needed.

The PML pan has posts cast into the pan on the inside to support the stock filter. These filter supports hold the filter in the same location as the stock pan.

The 2WD filter is on the left and the 4WD filter is on the right.

Either of these filters should work with this PML pan. Some people prefer the 4WD filter because of the longer pick up.

About Gaskets

PML recommends a flexible cork or cork composite gasket for this pan, such as this:

This cork gasket is a replacement for Ford OEM part number E9TZ-7A191-A. We ordered it from and their part number is 3072A. This gasket will work with E4OD, 4R100 and 5R110 transmissions.

We do not recomment hard, reusable gaskets for our pans. These gaskets work best with stamped steel pans.
