- 1971 Mustang, original 351ci Cleveland 4V and FMX automatic transmission. 3.0 positraction rear
I have a 1971 Mustang 2 door hardtop which has been in the family since new. It has an original 351 Cleveland 4V and FMX 3 speed automatic transmission. It has a 3.0 rear. The vinyl top is original.
At 65 MPH the engine is turning 3,000 RPM and it feels like it needs another gear (4th). Is there any way to replace the current FMX with a 4 speed automatic transmission and if so what transmission?
