I just noticed today that when I put the car in nuetral and let out the clutch pedal that a fairly loud hum comes from the tranny. This stops as soon as I press the clutch peddle back in. Any ideas before I get under the car?

 

probably a bearing noise I have found that the most common failure is the rear countershaft berring. if the noise goes away
in fourth and comes back in fifth than it is that berring.
