and find all the laments from Classic 900 owners who went to a quickie place and found, after it was too late, that the crew had drained the transmission, added 4 quarts and a filter to the motor without checking the dipstick, and then sent them on their way with a dry transmission and a drastically overfilled motor. It only takes a few miles before both are ruined. I suppose the same could happen with many other transaxle cars, but the SAAB does have the two drains in the same casting, although with very different plugs, and anyone with even two days of mechanical experience should recognize the difference in smell between the two lubricants.
