A friend had a recently rebuilt C4, so we put that in ... and it lasted DAYS.

The biggest complaint I ever had with the FMX was (as I said earlier) the convertor stall speed. It was just plain embarassing. ......

Shortly after fixing the transmission, the car was stolen ... resulting in a broken driveshaft, a hole in the floorboards, and a 3-piece (exploded internally) transmission!

If it wasn't for bad luck, I wouldn't have any luck at all!

Did I say STOCK C-4? Where would you get a NOS C-4 anyway?
So you found one bad used C-4. ok, so what? You had a bad used C-6 too.

C-6 came out in 1966 models.

The FMX/cruise-o-matic evolved from the 50s Ford-o-matic and was used until 1980.
Never saw a 428 with an FMX.

Before 66 muscle cars used the Lincoln big transmission, a cast iron cruise-o-matic. Used in FE and MEL Lincolns and T-Birds, etc. (Check out Tasca's first 62, 63, 64 Thunderbolt cars-- ya 62)

Small block C-6 came in early 70s 351W vans mostly.

C-6s were used mostly behind big block and heavy vehicles.... 351W, 351C, 390, 410, 428, 400, 429, 460.

70s cars: 351W had C-4s, 351Ms mostly FMXs, 351 Cs FMX, 400s had C-6s.

Geez no wonder you went to Chevys, with all that bad Ford
