I have the clutch lockup in forward and reverse. I have taken down the bell housing and found a broken cylinder in the clutch plate axis. See the photo for reference. It seems that this the cylinder part of the release bearing. I have replaced the clutch plate, cover and release bearing. After putting everything back. I still have issue. Forward seems to be alright however reverse gear will cause lockup. The only way to get out of it is to turn off the engine and put the gear in neutral. I have had my gear shaft bearing replaced 2 years ago. Does anyone know how reverse lockup occurs and how to fix.
