    700r4 no gears

    sorry i didnt say earlier. my car will move back and forth if rpm,s high, around 3500, didnt make loud sound when this happened.i launched from footbraking, and when it shifted the rpm's hit the rev limiter.done from there. TCI tech don;t have even a clue.what gives there build?

    Chance you could of broke the convertor. if thats the case it more than likely threw metal through the pump and all through the trans.

    what size of engine are you running and how much hp you putting to it? Are you racing it all the time or street/strip?

    Company i work for, we have several stages of 700's. from cruisers to 700 hp street strip supercharged cars. From what we've seen....the tci streetfighter is no more than a "stock" rebuild with a shift kit and a couple updates. They say rated for 450 hp but thats a little overrated especially when you put it in a heavy car like a chevelle.

    Feel free to call or email us and talk to one of our techs. Im sure they can help you with the setup you have now or get you into the right setup that will work and mainly last.
