I just spent a duece attempting to eliminate an intermittant chugging problem. It can happen anywhere from 40 mph up, usually while cruising at speed, then backing off on the gas, then giving it gas (but not flooring it). Not limited to this though. Sometimes dosen't happen for days, then daily. I took it to a reputable trannie shop. THey said it diagnosed fine. Anybody got a clue? Please e-mail rrhart@bellsouth.net
