I've recently changed the pressure plate, clutch, throw out bearing, and even turned the flywheel. The products are all Centerforce Stage I except for the stock flywheel. This was all done about 3000 miles ago. All of a sudden I started hesring a noise coming from the trans. The noise is like a loud humm. The only time you hear it and also feel it is when you press on the clutch. The car can be in motion or sitting still. This only happens once in a while. The only way the hum goes away is by releasing the pedal, wheter it is in gear or out. Any ideas. Thanks! (91 305 tbi t-5)
