What Can Cause a Whining Noise in a Transmission?


A transmission can prompt a whining noise if the operating system has malfunctioned, the gears are not operating correctly or the transmission fluid needs to be changed.

When diagnosing the problem and the cause of the whining noise, take note of when the sound is occurring, such as when the engine is idle, when shifting gears, when driving at a specific speed or when moving from drive to reverse. Narrowing down the specific time the whining noise occurs can help decipher the exact cause for a mechanic. Many times, instead of a costly repair, a simple transmission fluid change can rectify the problem.
