The Cruise-O-Matic
 
 
Introduced in 1951, the Cruise-O-Matic series
 
of three-speed automatics (which includes the FMX)
 
was used in Ford, Lincoln and Mercury passenger
 
cars until 1979, and in light trucks from 1968
 
through 1979.
 
 
They came in three configurations:
 
 
the small case (from 1951 to 1966)
 
 
the medium case (from 1955 to 1968), and
 
 
the FMX (from 1967 to 1979)
 
 
Early Cruise-O-matics had a filler tube that attached to the transmission pan.
 
 
FMX transmissions filler tube slid into the main case.
 
 
The Cruise-O-Matic transmissions are easily
 
identified by their design, which incorporates a
 
cast-iron main case (unlike all other Ford three-
 
speed automatic offerings) with separate aluminum
 
bellhousings and extension housings bolted to it.
 
The Cruise-O-Matics should be avoided in performance
 
applications as very little is available in the
 
way of aftermarket performance parts other than
 
shift kits. The Cruise-O-Matics were also offered
 
with all three bolt-common V8-pattern bellhousings.
