Sometimes when I switch into gear, forward or reverse, my Ranger seems to already have the clutch engaged. This has never happened before. There is no lag before it moves. I also noticed that when I come off of the gas, I think I'm getting the belt slapping the cover. I also have the rattling sound from what sounds like the clutch that started recently which many guys say they've had, although mine only started recently. I've never replaced my belt. I checked it recently and it doesn't appear worn. Any ideas?
