I have a 2001 rubicon with 7420 miles. I have not driven it lightly. Just one day is stopped moving but only in 5th gear and then it goes slower. It idles just fine but when you rev it up it seems to bind, and also in 1st gear. There are no codes and I have reset the transmission. There are no noises. I have changed the angle sensor and checked the oil pump chain. What is the toubleshooting sequence.
