I have a 1981 CJ5 with the 151 motor and the SR4 transmission. I had the SR4 rebuilt last winter as a bench build which appears to have gone well. When I removed the trans, I didn't take the bell of the motor so I never did a good visual inspection of the clutch. I've driven it 5 times now since the re-install of the trans and new slave cylinder and the clutch pedal started feeling crunchy and it's randomly slipping now in all the gears. I've had a clutch go out on me before and the slipping is definitely the same. The odd part is that I can push the clutch in once more after the slipping starts; and it goes back to normal.
I'm guessing it's the pressure plate or throw out bearing that have failed, but I also wanted to get some opinions on if you think it could be something that may have broken in the trans that was just rebuilt.
