    What would I need to do to swap a c4 to a 4 speed toploader in a 1966 ford fairlane what modifications to the body would need to be done to do so? Is there brackets for the clutch pedal and would i have to modify the body at all? Thank You!
  5. C4 into 1964 Fairlane

    Fairlane Pages
    Hey all, I'm new to the forums so please go easy on me. I'm putting a 289 with a C4 into my '64. I'm completely in the dark about which motor mounts and crossmember mounts to use, as well as which crossmember would be the proper fit. I'm very much an amateur so if you have any advice aside...
  6. C4 Transmission Shudders 1st-2nd

    C4 Transmissions
    So my trans started acting up about 3 months ago. The transmission can't decide if it wants to be in 1st or 2nd gear when rolling slowly from idle to slight throttle. It shudders/ clunks back and forth from 1st-2nd. This would occur between 8-12 mph and usually on a slight incline. I took it...
  7. C4 warm up time needed/what is the problem?

    C4 Transmissions
    I got a 1965 mustang which I think it may or may not have morning sickness.

Mine I can start...

    C4 Transmissions
    I have a 1971 302 V8 and am looking at getting a 1979 C4 from a 300cid straight six. I was wondering do I need a flex plate and torque converter? Can I use the torque converter etc. with the V8 from the straight 6 or would I need to find one that was originally used with a 302? The 302 came...
  10. almost reliable

    Galaxie Pages
    I almost have this thing running. About every 10 miles something else pops up to fix. I drove my 67 galaxie with 351w w/c4 to work and back (15 miles each way). I have test driven it around the block a few times with no problems. It drove beautifully. c4 was a little strange to get used to...
