Okay, here's the facts..........2002 Mustang coupe, V6, Auto-transmission..... Started developing a whine about the pitch and frequency that you'd hear in a movie from a remote controlled airplane; It's louder in the cabin, almost impossible to hear if you open a window listening for it, and seems definitely towards the front; Changes pitch when the transmission shifts and engine revolutions increase but it's probably important to note that the transmission is shifting perfectly, no fluid leakage (didn't lose a drop between oil changes), no slipping, jerking, etc. No other symptom that might mean transmission failure; Originally it only happened while driving, never when stopped or starting, now it's starting to be there when stopped and this morning when I was stopped I threw it into Park just to check and it continued; Worse and louder when cold, and disappears almost entirely after about 1/2 hour of driving; I had a friend of a friend who's a mechanic drive it yesterday and he said transmission, but in my experience, transmission noises don't get better as you drive, and I have no clue whether he's a decent mechanic or not. Nor do I find an unidentified "whine" as any one of the symptoms of transmission or torque converter failure, etc. I do have an appointment on Saturday with my mechanic, but I'm freaking out. It's "my baby" you know? Ideas, suggestions, help? Anybody who's mechanically inclined have any clue whatsoever what it could be? 'Rani
