Some vehicles may exhibit a "buzz", whining", or "moaning" like noise from the transmission when reverse gear is selected. The condition is caused by a resonance of the transmission regulator valve. Our technicians tell us that the repair involves replacing the transmission regulator (aluminum) valve with a steel one.

Often when put in reverse you hear a grinding squealing noise. Never when I take it to the transmission shop. Just home in the drivewa.
