1989 Trooper Transmission Question

Hello all,
I know that the 2.8L engine in the '89s is a GM product, but is the rest of the drivetrain also a GM product? That is, could I take the entire
transmission + transfer case assembly from, say, a 4x4 S-10 and throw it under the Trooper? If this is the case, I wonder how many yards and parts dealers are aware of this. I am in need of a replacement tranny after a lovely throwout bearing mishap and this would help to broaden options as far as looking through salvage yards, etc.
On that note, what is the best way to go as far as transmission repair? According to the mechanic ( I haven't yet gone in to look myself ), the transmission case was severely damaged by the throwout bearing and subsequent clutch damage. However, it sounds as if the actual transmission is still fine ( I was able to drive it to the mechanic with no problems, other than the terrible noise and clutch grinding. Didnt have any problems in any of the gears ). His suggestion was to just pull the whole thing and toss in a new transmission, and I assume the 4x4 transfer case goes with that. Is there a way to avoid this, and if so, what is the most cost-effective:
- Find a used transmission somewhere and hope it's relatively cheap
- Find a rebuilt/reman transmission, same hopes as above
- Find just a transmission case, and have the mechanic put the old tranny into it (Given that he isn't a specialist, I am leery of this option)
- ???
I am going to try and get to the mechanic tomorrow to check it out myself, to see exactly what he is talking about. They only opened it up Friday afternoon; we were thinking it was only a clutch replacement job...sigh.
Thanks, -Mark Wardell

If you only damaged the bell housing and not the shaft and associated bearings you might be able to get by with just changing out the bell housing. With most trannies the bell housing just bolts on to the rest of the tran. However, if the throwout damaged the rest of the trans when it went then it is best to replace the tranny.
Good luck
