Clutch and Transmission

AUTOMATIC TRANSMISSION
Two types of automatic transmissions have been used in Mavericks and Comets. A fully automatic C4 transmission is used in all 1970—77 applications. A semi-automatic C4S transmission was offered on the 1970 Maverick only and was dropped in 1971.

The C4 automatic transmission is a 3-speed unit capable of providing automatic up-shifts and downshifts through the 3 forward gear ratios, and also capable of providing manual selection of First and Second gears.

The C4S semi-automatic transmission is a manually operated power shift transmission which does not require a clutch pedal. The C4S is similar to the C4 fully automatic transmission except for changes in the control valve body and that the vacuum diaphragm, throttle rod, governor and the inner and outer downshift lever assemblies have been eliminated.

Both transmissions consist essentially of a torque converter, planetary gear train, two multiple disc clutches, a one-way clutch and a hydraulic control system.

The only adjustments on the transmissions are the intermediate and low-reverse bands.
An identification tag is located under the lower front intermediate servo cover bolt. The tag shows the model prefix and suffix, assembly part numbers, and the built-date code.
