I did take the car to the local SAAB dealer, they immediately told me to replace the transmission. ($6000.00 - 7000.00) (Dealer did not inspect, just listened to the noise.) As I mentioned in the first post, the transmission does function as it should. I'm going to try your suggestions, starting with the ATF and filter change. If it turns out to need replacing I may just have it rebuilt. I have also been on the lookout for a used tranny, but seem to be hard to find. Thanks for the response, Kirk,
