I have searched for this topic and it seems that this is a common problem with mustangs. My car is a DD and a few days ago out of the blue my car has started the famous "chirp" sound that goes away when I push the clutch pedal in and it goes away after the the car warms up. The car shifts fine. Now does this noise come from the TOB or the TOB sleeve? What kind of problem will it cause if I drive around with this (other than annoying)? What is a good TOB and sleeve to purchase? I will probably NOT have a shop do this since my funds are low and I'm starting school next week and this is my only car to commute with .
