What are the symptoms of a slipping transmission in a Mercedes-Benz?
1 Answers
The symptoms of a slipping transmission in a Mercedes-Benz are: When starting, pressing the accelerator pedal results in high engine RPM but slow vehicle acceleration. During driving, deeply pressing the throttle leads to sluggish speed increase. When climbing a slope, the engine revs high but the car moves slowly. When shifting into a certain gear while moving, the engine RPM suddenly rises but the vehicle speed increases slowly. The feeling of transmission slipping: Transmission slipping is accompanied by jerking, naturally causing a sense of hesitation. When pressing the accelerator, the engine responds quickly with rapid RPM increase, but there's no sense of acceleration push, giving a feeling similar to revving in neutral. Reasons for transmission slipping: It may be due to severe wear of the clutch, brake or one-way clutch themselves, excessive clearance of clutch plates causing slippage. Or it could be from adding too much transmission fluid, which when violently agitated by planetary gears produces excessive air bubbles leading to slippage. Another possibility is using non-specified transmission fluid, as some inferior fluids can accelerate aging, swelling or failure of internal transmission seals, resulting in slipping.
