Editing Transmission identification

{{youcanedit}}
== PREAMBLE ==

The purpose and function of this page is to acquaint people with the identification of popular North American made transmissions based on pan shape, case outline, and OEM numbering. This page also offers overall dimension, gear ratios and number of gears available in each transmission, and originating year, make and model.

====Ford-o-matic S3====

[[Image:Cruise-O-Matic_I_D_7.jpg‎]]

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).
#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.
