Jumping out of 2nd & 4th

My daughter’s 2002 Saturn S-series coupe has a manual transmission. Lately it has been jumping out of 2nd gear, and occassionally 4th and reverse. What is the most likely cause?

I would look at the shifter, shifter cables, and cable adjustments. Make sure that the transmission selector is going into full detent on 2nd, 4th, and reverse.

It is a little early to be having transmission problems unless the car was abused.

Good luck on this.

Motor or transmission mounts is another possibility.
