Just picked up a 2003 Cobra today with 12k miles on it. During the test drive(s) the transmission shifted fine without any problems. After taking it home and driving it easy around town, I couldn't get it into 1st gear when at a full stop. I could get it in after shifting to 2nd first, but it doesn't feel like it should. It goes into 1st smoothly if i'm moving slowly, but once I stop it's a pain. Am I looking at a clutch cable adjustment issue, streched cable, or a tranny problem?
