Ford C4 - C10
The ford C4 was a three speed, medium duty automatic transmission which was introduced in 1964 and produced through to 1986.
The early model c4 (1964-1969) used a .788 inch 24 spline input shaft which was upgraded in 1970 to 26 spline .839 inch. The upgrade also included a matching clutch hub of 26spline. The 1971 Ford C4 went to a 26/24 spline input shaft, meaning the torque convertor side is 26 spline and the clutch hub is 24 spline.
