Charlie's Garage Sale


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.

Band adjustments:
Intermediate = ¼" servo travel
Reverse = 1½ turns

Gear Ratios:
2.40:1 1st gear
1.47:1 2nd gear
1.00:1 3rd gear
2.20:1 reverse

Exploded views are of the Fordomatic, but the FMX is very similar as to the appearance of the parts.
