When does the whine of the transmission increase?

When does the whine of the transmission increase?

But accelerating at any speed increases the whine. The pitch of the whine goes higher along with the sound volume of the whine increasing as engine RPMs increase. When a shift point is reached and RPMs drop the loudness and pitch of the whine drop. *Whine not heard when engine is cold. Whine only heard once engine is warmed up.

Why is my engine RPM so high while driving?

Driving at a higher RPM will demand more fuel / emissions and cause the engine to work harder.

When does a car whine when in low gear?

Whine is heard ONLY when gas pedal is depressed and especially loud when car is in low gear starting up from a stop or when accelerating uphill.

When does a manual transmission make a whining noise?

A manual transmission is only turning when the car is either in motion, or when the transmission is in Neutral and the clutch is engaged (your foot is off the pedal). So sounds that occur while the car is stationary and in gear are most likely associated with the clutch.
