C4 Tranny Interchange

Was the stock C4 tranny in a "77" used in anything else? Like F100/250 4x4, direct crossover, not changing bell housings, tailshaft etc?

Used in lots of stuff, bell depends on engine series.

2wd to 4wd, tailshaft housing probably diff, if C4 used for 4x4.

Doubt you'd find a C4 in a 250.

D3BZ-7976-A .. C4 Converter Housing

Fits: 1973/77 Bronco / 1973/74 LTD 351 / 77/78 LTD 351/400 / 73/76 Torino 302 w/floor shift / 1976 Granada/Maverick 302 / 1975/76 Granada/Monarch 351W / 1977 Granada/Monarch 351W w/floor shift or console (don't ask me, that's what the book sez).

Prior to 1980

No: 302 (or 289) 4WD's exc 1966/77 Bronco's

No C4 4WD's exc. 1966/77 Bronco

No direct crossover, what fits in a Bronco won't fit without swapping parts.

Example: C4 extension housing = 1973/77 Bronco only.

The main C4 case is also unique to the Bronco. All other C4's had case fill dipstick tubes. The Bronco C4 had the dipstick tube in the pan itself. You can use the case fill transmission, but you would need to block the hole in the case.

Actually the pan fill C-4 came out in 1970 and was used in many applications from trucks to Torinos. The case fill was still used on the smaller cars. The Bronco bellhousing is longer than the car.

Never seen a pan fill C4 on anything but a Bronco. I've parted out several
C4's over the years and have never came across one if they exist. Number Dummy, can you confirm this?

Where would the bellhousing be longer? Are you referring to depth for converter clearance with small and large TC's? According to what ND posted, there are several car applications that share the bellhousing with the Bronco. Maybe the Mustang (and similar performance models) used the small torque converter and housing?
