Every time I drive the saab around I get a hard thud right after i upshift. Is this an engine mount? For a better example lets say im just sitting in the car while its in neutral....lets say if i tap the gas really quick you hear and feel a hard thud, then the rpms go up...thats all i can describe.....especially while upshifting i try to take it easy on the accelerator so it doesnt happen but I think im gonna have my shop take a look at it tommorow. Any ideas?

sounds like a mounts issue indeed.

Take a look at your dog-bone mounts to see if they are ripped. Quasimotors has a great writeup on mouts here (http://www.quasimotors.com/mountinfo.htm). Also, check your tranny mount (you will have to pull out the wheel arch trim to do it)

I recomend the powerflex pollys in place of the rubber OEM bits since they life longer and improve shifting.
