What is the issue when a Mercedes-Benz makes a noise upon shifting gears?
1 Answers
Possible reasons for the noise when shifting gears in a Mercedes-Benz are as follows: 1. Transmission failure: Damage to the transmission housing, or long-term wear and deformation of the transmission housing and bearing seat holes. This type of noise is loudest when shifting into low gears, gradually decreasing as higher gears are engaged, and is minimal in direct drive. 2. Gear failure: Due to the fracture of individual gear surfaces, impact occurs during meshing. When shifting into this gear, strong impact and vibration are generated, causing resonance in the transmission housing. 3. Drivetrain failure: Poor technical condition of the external drivetrain (clutch, drive shaft) of the transmission, leading to impact and vibration during use, which causes transmission resonance and produces resonant noise. This type of noise is often irregular and may occur occasionally within a certain speed range.
