was driving to work and went to change gears when the clutch peddle stuck to the floor started to hear creaking noise just before the incident but no other indications that this would happen before that. dealership is saying that its a slave cylinder and that the entire clutch needs to be replaced, because the failure may have caused the clutch to over extend but has no proof of this, as well which makes no sense. am I crazy here or am I being taken for a ride?
