I think my TQC is slipping.....(i think...high pitch whinning noise at idle, goes away when I rev or accelerate). Is this an indication of my tranny going out? Or can something be done? The tranny has 167,000 miles (lol), and the fluid level and color is fine...i changed it about 4 months ago. Oh yea, and it drives fine, but just yesterday started feeling a lot slower (noise started yesterday)....thanks
