    Hey there. You'll also need the wiring harness & computer. The computer on an auto controls both engine and tranny. But on a manual, the computer only controls the engine.

    Totally wrong on a 91 the auto is a 700R4 which is controlled by a TV cable not through the computer at all.
    Please don't help people if you don't know what you are talking about.
