I installed a 1995 transmission in my 1997 CSE Posted by JerseySaab [Email]  (#666) [Profile/Gallery]

In the summer of 2017 I installed a used autobox from a junkyard 1995 9000 in my 1997 CSE. (The original failed at over 300,000 miles with symptoms indicating a broken band.) The only snag on installation was the control lever arm was different on the '95 trans. It was easy though to swap the part from the '97 transmission to the "new" one. It's worked fine since installation.
This suggests that at least as far as fitment and basic operation goes, a 1995-1998 transmission should work for you. (I don't think there were any changes made to the trans for '98.)
It probably is best to have a mechanic do the job but it is quite labor intensive so will be expensive. I did it myself but quite honestly it quickly became apparent that I'd bit off more than I could chew, particularly for an old guy with arthritis. There is a LOT of disassembly involved. However once the job was started there really was no choice but to finish it. Fortunately it turned out OK. Had the used transmission been bad there was no way I was going to re-do that job even though the junkyard guaranteed the trans. (It only cost $175 so was not a big financial gamble.)
Moving forward the future is pretty grim for 9000s with the automatic transmission (I have two of them) because there is little or no support for them at this point and almost nobody knows how to work on them. It's possible some parts may be sourced overseas since the trans was used more widely in Europe than on cars sold in the U.S., where it was only ever found on a handful of low-volume cars decades ago. Best advice I can give is if you can't go for a manual trans conversion, once you get the automatic sorted out change the fluid frequently and don't abuse it.
You didn't say exactly what went wrong with your transmission. There are a couple of common problems that might lead one to believe the trans has failed or is failing but are relatively easy fixes. When the governor seals go bad, automatic shifting is very erratic but you can shift manually with no problem. It feels like the transmission has gone bad but it hasn't. Replacing the seals is not difficult to do. (When these cars were more common you could sometimes pick one up cheap with a "bad transmission" when all it needed was $50 worth of seals and a few hours work.) Another problem is engine speed flaring on the 3-4 shift. You might think it means clutch or band linings are shot but there was Saab TSB stating that this is caused by a weak or broken accumulator spring in the valve body.
