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 very similar to the C4 transmission but could handle greater power. It was used primarily in trucks, although it was also used in some larger cars with larger engines (see Ford FE engine and Ford 385 engine). 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.



The C6 was replaced by the E4OD which was modified to include a fourth forward speed and electronic shift controls, replacing the hydraulic control mechanism of the C6.



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.
