944 gear shifting problem

[Larry Herman]

David, if you can shift it with the engine off, and it creeps forward when the engine is running and the clutch is depressed it pretty much limits the problem to lack of disengagement.  That would be one of 2 things, either the clutch is not releasing due to insufficient throwout travel, or the clutch disk is dragging between the pressure plate and flywheel.

Since bleeding helped somewhat, I would look at the clutch slave cylinder first, and then the clutch master cylinder 2nd.  Only after I knew that both were working properly would I pull the trans and look at the clutch.
