PML's extra capacity transmission pan for fits Ford C6 transmissions which are found on 1960's and 1970's full size cars and pre-1988 Ford vans, motor homes, SUVs, and trucks. For example, the C6 transmission is commonly found on:

  • Bronco, 1978-1988, 351 engine
  • F150 truck, 1970s
  • F250 truck, 1966-1988, with 351, 460, 6.9 or diesel engines
  • F350 SRW truck, 1966-1988, with 351, 450, 6.9 or diesel engines

This PML pan design features steps for vehicles with cross members or other clearance issues. The extra capacity comes from the deep sump in the middle of the pan. Please check your vehicle carefully using the dimensions above for clearance and to verify the transmission installed on your truck or SUV.

Bolts and magnetic drain plug included with PML Ford C6 deep pan

Included with PML Transmission Pan

PML includes new mounting bolts and a magnetic drain plug with each pan. PML includes new mounting hardware since the stock bolts would not be long enough. The flange of the PML pan is much thicker than the stock pan for a secure seal to the housing.

PML Ford C6 Pans Compared to Stock

PML also makes a stock capacity C6 transmission pan, PML Part Number 11064, for applications that cannot accommodate a deep pan. The stock capacity pan is intended for the Ford 1960's and 1970's full size cars with the C6 transmission.

The PML stock capacity C6 pan will not clear the frame cross members that run under the pan on some Ford trucks.

Drain and Bosses for Temperature Sending Units

The drain is located on the driver's side of the transmission pan. We includes a magnetic drain plug with each order.

This pan has two bosses (thick, round areas) that can optionally be machined for a temperature sending unit. If you wish PML to drill and tap for a temperature sending unit, there is a machining charge. Select this option in the shopping cart.

PML Ford C6 deep pan back and passenger side

In 2017, we moved the boss on the passenger side to the inside. In a few configurations, the drive shaft runs close to the pan and contacted the boss that had been on the outside.

All bosses for black powder coated and as cast finish are on the inside to maintain outside clearance (as of November 2017).

Gaskets and Filters for PML C6 Pan

This picture shows the inside of the PML pan.

PML designed this pan to work with stock gaskets and filters.

Filter supports are not needed as the filter bolts on to the valve body. The fluid level is at the same place with a PML pan or a stock pan so an extension is not needed.

Ford C6 transmission filter kits

This shows two possible filter kits for Ford C6 transmissions. They both include a rubber-cork type gasket, which we recommended for use with a PML transmission pan.

These are from Fram and have part numbers FT1025a and FT1037a (longer pick-up spout show on right).

A customer with a 1987 F250 purchased the the FT 1055a C6 filter, which he used with his stock pan. This filter has a pick up tube connected to the filter with a gasket. Although the gasket holds the tube in place, the tube probably rested on the bottom of the stock pan. The PML pan is NOT designed to support a pick up tube. If the tube should fall out of the main part of the filter, severe damage could result.

Letters on Housing Causing Interference?

On a 1989 Bronco, a customer reported that the transmission housing had letters cast into it next to the flange. The letters were raised and hung down slightly below the housing flange mating surface.

Because of the lettering, he was not able to get a good seal. The PML flange is thick and wide and extended slightly over the edge of the housing flange, hitting the letters. He ground of some of the flange on the PML pan with a belt sander. This allowed the pan to seat correctly and snugly.


1978 F250

Ed installed this PML transmission pan on his 1978 F250. The 400cid engine is solid and the C6 is recently rebuilt. He tows a 11,000lb toy hauler. The truck has a Dana 60 front end and he replaced the Dana 60 rear with a Dana 70hd dually axle and converted it to disk brakes. And that's just a few of the upgrades.
