    Auto to manual conversion info

    Back in 2001, I converted my automatic to a 5-speed manual. I think I was the second person to do this to a 3S, Hans from GZP was the first and this list actually came from him. I was going through my filing cabinet and ran across the parts list, so I figured I'd post it here for anyone interested in doing it.

    1. Drivers Side Half Shaft
    Part No. 1990 -1992.5: MB526786
    Part No. 1992.5 - up: MB886588
    2. Cluth and Brake Pedal Assembly
    Find at a junkyard
    3. Flywheel
    Don't have a Part No., but could buy used, new OEM, or new aftermarket
    4. Clutch Assist
    Part No. 1990 -1992.5: MD770482
    Part No. 1992.5 - up: MD770482
    5. Clutch Release Cylinder Tube
    Part No. 1990 -1992.5: MD740917
    Part No. 1992.5 - up: MD740917
    6. Clutch Release Cylinder Hose
    Part No. 1990 -1992.5: MR151526
    Part No. 1992.5 - up: MR151526
    7. Clutch Master Cylinder Tube
    Part No. 1990 -1992.5: MB555280
    Part No. 1992.5 - up: MB555280
    8. Clutch Dampener
    Part No. 1990 -1992.5: MD741416
    Part No. 1992.5 - up: MD741416
    9. Clutch Master Cylinder
    Don't have a Part No., but could by used or new OEM
    10. Flywheel to crankshaft bolts
    Part No. 1990 -1992.5: MD113400
    Part No. 1992.5 - up: MD113400
    11. Clip for shifter cables
    Part No. 1990 -1992.5: MB307554
    Part No. 1992.5 - up: MB307554
    12. Clips for shifter cables
    Part No. 1990 -1992.5: MB367526
    Part No. 1992.5 - up: MB367526
    13. OEM Clutch
    Part No. 1990 -1992.5: MD735647

    14. OEM Pressure Plate
    Part No. 1990 -1992.5: MD739223
    Part No. 1992.5 - up: MD739223
    An option would be to get a stronger aftermarket clutch/pressure plate setup
    15. Throw out bearing
    Part No. 1990 -1992.5: MD706180
    Part No. 1992.5 - up: MD706180

    20. Transmission mounting braket
    Don't have a Part No.
    21. Transmission
    Part No. 1990 -1992.5: MD995667
    Part No. 1992.5 - up: MD970886
    22. Reverse light wiring harness
    Don't have a Part No.

    As hard as it sounds, it's actually a pretty easy and straight forward conversion. The hardest part was replacing the automatic brake pedal with the standard clutch/brake pedal unit. You have to drill holes through the firewall for the pedal assembly to attach to the clutch master cylinder on the engine side of the firewall. The only thing really tricky was the TCU plug that used to go to the automatic transmission. You have to add a jumper wire on this plug in order for the car to start, and I can't remember which plugs are jumpered. Also, the axles you need are determined by what year your new manual transmission is. If you have a 1990-1992.5 transmission, you need axles from the same years. If you have a 1992.5 and newer transmission, you need axles from a 1992.5 and newer 5-speed car.

    lol, yes it was! and I still have the 11 year old print out of it! hah. I never did have to go buy all these parts, thank God. I was able to score a complete transmission with everything I needed from some guy in Oregon IIRC. I paid like $350 for everything.
