Sounds like something isn't engaging properly when you select reverse. Are the forward gears all working properly? Have you tried manually selecting 1 and 2 as well as using the normal 'D' position? From what I've read you will probably need to have the transmission removed to service it which as you'll know means the engine out as well. This can be good and bad - lots of work to prepare, but if you need to do stuff on the engine which can't be done or isn't easy to do with the engine in the car (such as crankshaft seals, oil pump work, etc.), you could do engine repairs while it's out of the car and as someone else suggested put a manual tranny in place of the auto if you'd like to. Only thing with that is you need to replace other stuff like the selector assembly and linkages (since the manual selector and linkage is very different to the auto one), and run a line from the bottom of the brake fluid reservoir to feed the clutch system. In our auto-tranny C900's that extra fluid line doesn't exist. Also when you remove the auto tranny you'll need to remove the oil cooler which is either going to be the inline-with-bottom-radiator-hose type (likely since you car is an 83 like two of mine), or the under the right-side corner of the bumper type. If it's the bottom radiator hose inline type you'll need to replace that hose since the cooler makes it into two sections. I want to replace one of the auto tranny's with a manual eventually - the donor car I have here has a manual tranny but it's currently beyond my budget to extract it, service it to fix anything wrong, and do the tranny swap in one of the running cars. It won't happen overnight but it will happen! lol Craig. -- Craig's Saab C900 Page at | Craig's Classic Saab Workshop - Sydney .au http://nospam/~c900 | http://www.classicsaab.net and other URL's Email: c900nospam.apana.org.au | For Saab 99/C900/9000 Enthusiasts World-Wide!
