The Ford C6 Transmission:
The Ford C6 is a heavy-duty automatic transmission built by Ford Motor Company between 1966 and 1996. It was marketed as the "SelectShift Cruise-O-Matic" Compared to its predecessor MX transmission, the C6 offered lower weight, less complexity, less parasitic power loss, and greater torque capacity for larger engines. It did this without exceeding the packaging dimensions of the MX. These design goals were in line with those of the C4 for smaller engines.
