The Ford C6 transmission was a heavy-duty automatic transmission built by the Ford Motor Company between 1966 and 1996. It featured three forward speeds and reverse, and was built around a Simpson planetary gearset.
It was initially built at the Livonia Transmission Plant in Livonia, Michigan, but production was shifted to the Sharonville Transmission Plant near Cincinnati, Ohio during the mid-1980s.
It was similar to the C4 transmission but could handle greater power. It was used in trucks and cars with large engines. Four case bell housing varieties exist for use with various Ford engines: small block, for the Windsor and small block Cleveland V8s; FE, for the 360, 390, 427, and 428 V8s; big block, for the 351M and 400 Cleveland and the 429 and 460 big block V8s; and diesel, also available on the inline 6. The small block case is relatively rare. The diesel case is similar to the big block case, but is not interchangeable. The transmission is very popular in the sport of drag racing today, with units equipped with manual valve bodies and transbrakes, some of which are air shifted. It is also widely used in off-road applications due to its reputation of being nearly indestructible. It does, however, have a reputation of greatly reducing performance as well as fuel mileage, due to the amount of power it requires to operate.
Applications:
The C6 core components were used to build Ford's 1st electronically controlled automatic transmission. The E4OD was introduced in 1989 and used in both light and heavy duty applications. The E40D has four forward speeds and electronic shift controls replacing the hydraulic governor control mechanism of the C6.
Applications:
The E4OD was updated in 1998. Ford renamed it the 4R100 in keeping with new naming standards. It was largely the same as the E40D, but with some reinforcements to address reliability concerns.
