                                The Ford C4 automatic transmission, popular in many classic vehicles from the 1960s and 70s, has a total fluid capacity of about 8 to 10 quarts. A complete fluid change, including the torque converter, is crucial for optimal performance, though a pan-only drain will require significantly less.
