    Is it very difficult to change a stick shift car into an automatic transmission? :confused: Thanks

    it would be a lot easier than changing from an auto to stick. just gotta get rid of the clutch pedal and linkage. you will need to change from a fly wheel and clutch setup to a flex plate and torque convertor, and different bellhousing. also you'll need a floorshifter, unless you change the whole steering column too. can't think of anything else offhand. oh, might need to change the tranny mount.:)

    If its a V8, I may be interested in your old parts... I hope to go the other way, auto to stick.

    Must not have been many manual tranny Mavs/Comets in Alabama, I've never even seen one...

    Trust me on this:
    Just take you clutch linkage off and store it away.
    Don't worry with changing the pedals at all.
    Just push your clutch pedal to the floor and tuck it under the front edge of the carpet.

    One day, when you sell the car, want to go back stock, or want to mod it and put a 4 speed in... you are set.

    KEEP EVERY LITTLE PART!
    No matter how simple it seems at this moment.
    You will be glad you did one day.
    That stuff gets more valuable all the time and even your car's next owner might see it as a selling point when he buys the car from you.

    Edit:
    I guess I should address your question...

    Your speed cable is different.
    The auto trans has it going into the tailshaft on the other side of the car, so it is longer and comes in from a different direction.
    I went from auto to manual, so I had a similar problem.
    I routed mine around to the other side, but it had a soft bend in it that the cable didn't like. It failed pretty shortly thereafter.
    Try to reroute yours, but do it so that there are no curves sharper than what it has now. If you can't get it to work, you will need a cable.
    For ease of shifting, you should probably use a cable shifter. I used a Z-Gate B&M, but there are many to choose from.
    That way you don't have to fool with linkage or cutting a hole in your floor.
    A cable shifter just uses a small hole that you can drill into the floor.
    A C4 auto will bolt right in. No worry with the driveshaft, crossmember, and such.
    C4s varied some from year to year, so all your auxillary parts need to match the year/style tranny you use. Converter, flexplate, etc... The flexplate also needs to match the balance of your engine. If it is a v8 from the 70s, it is 28 oz balance. Later engines used 50 oz. The flexplate also has a load spreading ring that you will need that washers under the flexplate bolts.

    Thank you for all the answers.


    My wife wanted to know and I was not sure about it so I thought I would ask. I knew I could count on all of you smart guys. Btw, this has nothing to do with my comet (which is an automatic floor shift) it's a general question. Thanks :tiphat:
