Driving a 2003 9-3 Linear, manual, 63k miles. Anyone run into 5th gear "slipping" out into neutral? Just started this week. clutch appears fine. Smooth transition into 5th from 4th, just doesn't stay in gear. Can hold shifter in 5th and drive it this way, however feel it wanting to slip back. Not too thrilled about having to drive around in 4th as you may imagine. Has jumped out of 4th once or twice but all the time with 5th. No error codes or warnings from the car.... Thoughts? Appreciate any insight.
