This past weekend I was driving through Nashville and all of a sudden the transmission just popped out of gear. It only did it if i was in 5th or 6th. Then it started getting hard to get it out of 5th and shift into 6th like the clutch wasn't fully engaged. I have a DFX clutch that only has about 5000 miles on it and no track runs. I recently put in a new clutch cable, quadrant and firewall adjuster. Anyone ever run into this problem or have any ideas what might be causing this????
