Ok, a friend of mine cannot get his transmission in gear if the car is running. We suspect the clutch is bad. What is involved in changing the clutch? More my ERA the tunnel came out allowing access. Can you get access to the transmission and Bellhousing from the top or do you have to do it from the bottom? Are there any other things likely to cause this? He had been gradually having a great difficulty in shifting over the past few months so we adjusted clutch like 2 turns on the adjuster. Worked fine for a few weeks and now he cannot get into gear with car running. Looking for answers before we tear into it.
