Ford FMX transmission

FMX

Was used 1968-81 in many Ford products.

This is an hydraulically controlled rear wheel drive transmission. It has a cast iron case and an aluminum bell housing and extension housing. It is similar in appearance to the Fordomatic that was used since 1951 and the Borg-Warner BW8 and BW12, but almost none of the parts are interchangeable. 1968 was a cross-over year where the Fordomatic was used in some vehicles for part of the year before changing over to the FMX.

Rear cooler line is the cooler return line.
