Ford’s C6 is a 3-speed automatic, but a rebuild kit still must match the transmission’s year break, 2WD or 4WD configuration and the exact parts required. Do not substitute a C4, FMX, E4OD or 4R100 kit: those are different transmission families. Identify the transmission and inspect what is reusable before ordering. The first 7 are C6 overhaul or master kits; the final 2 are expressly labelled valve-body shift-kit near-misses that may complement a rebuild but do not replace friction, steel, seal or bushing kits.

Buying tips

  • Confirm the unit is a C6 and record its build year and 2WD/4WD configuration before buying any kit.
  • Read each kit’s component list: a master kit, overhaul kit, filter, band and bushing kit are not interchangeable descriptions.
  • A transmission rebuild requires measurement, cleanliness and service-manual procedures; consult a qualified transmission specialist if the condition or fitment is uncertain.
