The Ford C4 was a three-speed, light-duty automatic transmission introduced in the 1964 model year and produced through 1986.
It featured an aluminum alloy three-piece case (bell housing, main case, and tailhousing). This was significantly lighter than earlier cast iron Cruise-O-Matic designs. It also used a Simpson planetary gearset.
It was used with Ford's inline six-cylinder engines and small V8 engines (see Ford Windsor engines), usually up to 302 in³ (5.0 L). By comparison, the 351 Windsor and 351 Cleveland small and intermediate-block engines were backed by the medium-duty FMX. A few C4s were built with a big-block bellhousing to use with Ford 335 engines, notably the 351M, but these are very rare.
It is especially notable as the original automatic transmission option in the Ford Mustang.
Modified C4s remain popular with hot rodders and drag racers due to their simplicity and durability.

[edit] C5
The C4 was replaced in 1982 by the C5, which was essentially a C4 with a lock-up clutch in the torque converter to improve highway fuel economy. The C5 was phased out in 1986, replaced by the AOD. The production plant in Sharonville, Ohio was converted to production of the C6 transmission which was relocated from Livonia, Michigan, as the Livonia facility was converted to the front wheel drive AXOD.
