Rebuilding an automatic is a tough job. I'm a pretty good wrench and I've built four of 'em. Actually, it was only two, because I had to build both of 'em twice. There's no way of knowing what you got or what shape it was in when it went into the car. It is time to start looking for a new one. The Pontiac bell housng pattern is different than Chevrolet, so you need a Pontiac trans, Try eBay for an online rebuilder or used unit. There are several on there now, ranging from $ 150 to $ 650. Search for "Pontiac turbo 400" or "Pontiac th400". The tools required to buid your own are expensive.
