  • Swapping a 98 trans into my 97 Pin Question

    What do I do with the extra power pin. Can I use a harness from a 98 if not can I pull the pins and move them ?

        people have been swapping 98 transmissions into earlier cars for years.
        TCCOA has good articles and posts on the wiring changes needed.

          Yes, you repin the connector and use the 97 MLPS and TCC solenoid.

            you can delete the extra power pin as it is not needed. I wrapped mine up in electrical tape and inserted it in to the plug.
            re-pinning is done so you can retain your 97 controls/MLPS/TCC, etc
            I used a new TCC solenoid and trimmed the plastic connector down so it would fit under the circuit board.

            buy model-year specific parts (i.e. 97 MLPS, TCC solenoid, etc) and the re-pin takes care of making them work. Your PCM is still the same so the re-wiring allows it to communicate with the circuit board of the new tranny.

            best mod out there is a 98+ trans in to a pre-98.

            while its out, upgrade your converter to a mach 1/Marauder TC.

            keep in mind the angle of the plug you are staring at as you re-pin it...the drawings on TCCOA that is. (from behind, not from the front)

              If you have the external harness from a 98 M8, then you can use that to swap the 98 transmission into a 97 Mark VIII without ANY other changes.

              No repining, no splicing, just plug and play. No changes to any wiring (car or trans side). MLPS/TCC/Shift solenoids all have the same values.
