    automatic transmission
    ELECTRONICS

    need to know what color wires and where at exactly in the truck wher eits mountd and how and what next to and what color and size thing it is. sounds like you just need to find a good used harness, they easy to find, ive tossed alot of good harnesses 73-up i woulda gave up.

    good luck

    Sounds like some aftermarket thing. Might be a lockup converter controller that lets you change what MPH it locks?

    Never seen a GM piece that affects vehicle operation thats adjustable, at least like that /forums/images/graemlins/smile.gif
