Gearbox Malfunction light coming on. I think the shift lever module needs reprogramming.
The model you describe 42250 is not a model Saab, but I find an Aero model with the 2.0 engine. The gearbox light being on indicates a problem and you will need to have the vehicle scanned to see what code is received for further diagnosis. I recommend you contact a qualified technician who can test and scan the engine and transmission to diagnose the problem.
