Auto trans? I am not sure if that trans uses a vacuum controlled modulator but that sounds like the symntoms of a leaking modulator. If it has vacuum line down to trans pull off end at trans and see if tranny fluid pures out. If it does replace modulator and top up trans fluid. Smoke will go away after you stop the supply (eventually) <img src="/forums/images/graemlins/cheers.gif" alt="" />
