PML makes a case fill model (part number 10453-1) and a pan fill model
(part number 10453-2) for the Ford C4 transmission. The PML C4
transmission pans are the same except that the pan fill model includes a
brass fitting to allow filling directly into the side of the pan.
The C4 transmission was used in many Ford
vehicles between 1964 and 1986. The case fill and pan fill transmission
pans are the same except that the pan fill pan includes a brass fitting
to allow filling directly into the side of the pan.
The C4 case fill transmission pan fits 1965-1981 Ford vehicles with
the case fill C4 transmission such as Mustang, Bronco, Falcon, Pinto,
The pan fill model accomodates those C4 transmissions without a case
fill option. The pan fill pan is most often found on F100 trucks and
The C4 transmission is a popular performance transmission for racing.
These are usually modified or rebuilt vehicles. Racing is a demanding
application and the extra capacity and fins on this transmission pan
help cool the fluid for less wear and tear on the transmission.
A filter extension is not needed since the level of the fluid is in
the same location as with the stock pan. The Filter bolts on to the
valve body so no filter supports are needed.
