It sounds like that the transmission might require looking at by a specialist workshop for accurate diagnosis.
The most common cause of a noisy transmission is insufficient oil, causing the gears or internal assembly to hum or whir. If a noisy transmission does have enough oil, the lubricant may be contaminated with metal shavings or particles.
Insufficient or contaminated oil may cause the transmission to become noisy in some or all of the gears. But if you hear noises in specific gears, that gear's teeth or synchronizer may be worn or damaged.
Average prices for a good used transmission are around Â 350 excluding labor and clutch, if a new one is required.
