2 Spd Ford-o-Matic vs C4

[Anonymous]

Can I use a C4 trans in my '64, I6, 200 cid engine?..ZZ

Yes, but you'll have to make some modifications. The driveshaft will need to be shortened, you'll need to fabricate a rear tranny mount or purchase one from a vendor, you'll need the C4 tranny yoke, you'll have to modify the shift quadrant to match the C4 pattern, and you may have to modify your kickdown linkage. Try to find an early C4 and it will mount to your 64 block.

Here is the list of parts that I accumulated to change my 64.5 mustang from non-synchro 3 speed to a green dot C-4.

1. Auto tranny shifter, complete with T handle, mounting base and bolts;
2. Shifter indicator light, power wire and ground;
3. Auto tranny shifter bezel, with mounting screws;
4. Auto tranny shift linkage (z shaped bar that connects shifter to tranny gear selector arm;
5. Neutral safety switch;
6. Neutral safety switch wiring;
7. Tranny kickdown wire for engaging passing gear;
8. Engine shim plate (goes between engine and tranny at top);
9. Lower tranny inspection plate with correct mounting bolts;
10. Torque convertor with correct nuts;
11. Flex plate with correct bolts;
12. Auto tranny with correct bell housing and mounting bolts
13. Auto driveshaft with correct input yoke and two good u-joints;
14. Rear pinion flange for rear end (from car with auto tranny);
15. New U-bolts for rear end to hold rear u-joint to new rear pinion flange;
16. If converting car from stick to auto, you may want to consider replacing the 3 pedal (gas, brake, clutch) assembly with a 2 pedal (gas,brake) assembly.

I did not have to modify anything, everything just bolted in, but it takes time and patience.

I do not know if there is a difference in parts between the 2 speed and a regular C-4, perhaps someone else can provide that answer.

Keep us posted.

Thanks.

Kurt.

There is a difference going from the Fordo to a C4. Best option would be to grab a complete setup from a donor car, but that's not always possible.

Outstanding feedback. I'll be copying this and keeping in my records. Thanx..ZZ

I used a 1970 Maverick as a donor. The weird thing though was that the driveline apparently was the proper length. Can anyone confirm or disclaim this?

 

[Falcon62]

I can neither confirm nor deny (ahh that line brings back memories) the 70 Maverick being the right length, but I can post the length of the d/s in my Falcon and it's 53" center to center on the caps opposed to 54 1/2" for my son's Fordo equipped 61 Futura.
