The C3 was a '70s light-duty version of the C4 (It doesn't follow Ford's usual tranny numbering system - go figure :roll: ). Looks almost like a C4, but no cooler lines, no driver's side servo cover, and a 13-bolt oil pan. I think it was only used on light-duty four cylinders, like a pinto.
Depending on the year of your 200, it could be another version of the C4: the C5. More like a normal C4, but with a lockup torque converter. I think the only inline six to get it was the '81-'83 big bell 200 (looks almost like a smallblock Vee-Eight pattern, with a low-mounted starter).
Don't confuse it with the old 2-speed Fordomatic of the '50s and '60s...completely different beast.
