Whining in Reverse

I've just begun to notice that upon releasing the clutch in reverse, it makes a whining sound. This happens when I'm at the friction point. I'm thining the clutch may be bad, but my forward drive gears work fine. What do you think this sound is coming from?

All manuals whine when you back up. It normal

kinda like a little remote control car? mine does it too, its normal, i think every manual car has the potential to make that noise

Everyone that I have ever driven. See back up, and even ridden in has made that noise.

all manual transmissions whine when they back up because of the way the gear is designed. if i remember correctly, the forward gears are helical in design and the reverse one uses a straight spur gear.
