My 62 Chevy with three speed trans(three on the tree), 235 six cylinder crashes gears when I try to shift to low gear. Engaging the clutch doesn't seem to help. I have replaced the clutch slave cylinder and bled the system but nothing seems to help. It is worse when the engine is hot. One mechanic :confused: said it was the pilot bearing freezing up. The clutch and pilot bearings were replaced about 20k back. Any ideas before I begin tearing things down again?
