Ford C3 – ATSG (Automatic Transmission Service Group)

The C-3 Transmission was first introduced in 1973. This supplement brings the latest information to the rebuilder technician. This model  transmission is found in late model Mustangs and Thunderbirds.

The C-3 Transmission is a fully automatic transmission with three forward speeds and one reverse. It consists of a welded torque converter, a two unit planetary gear train, and a hydraulic system to control gear selection and automatic shifts. The planetary gear train is the Simpson Design with two gear sets in series yvith a common sun gear. Two friction clutches, two bands and a roller clutch are used to control gear operation.

Some of the differences in the late model unit are: The direct drum is now a metal stamping instead of a casting, the roller clutch inner race is pressed onto the rear case hub, where as the previous models the race was bolted into the case. The later models do not have a return spring in the reverse servo. The front seal has been changed in the late models and use the same seal as the A4LD. Note that the A4LD seal will not interchange on the 1981 and earlier C-3. If used on early models, front seal pop-out will occur.
