Possible Purchase: 98Z - HELP!
A replacement trans will run you about 1800.00 if he's really smashed stuff up inside. If he's managed to break metal off the internals of the trans (which it sounds like) and that metal has been bouncing around inside there then the only way to know for sure is to tear it down and inspect. Personally it doesn't sound like it's worth it to me. You could easily sink $600+ in parts into it and that's assuming you do all the work yourself.
