## Common Symptoms of Rough Shifting

Drivers of the 2016 Mercedes C-Class often describe a range of unsettling behaviors when their transmission isn't performing optimally. These can manifest as a subtle annoyance or a significant disruption to the driving experience. The most common complaints revolve around the feeling of the car lurching or hesitating when changing gears, which can be particularly noticeable in stop-and-go traffic or during spirited driving.

- **Harsh or jerky shifts:** The most common symptom, where the transmission feels like it's slamming into gear rather than smoothly transitioning. This can be felt during both upshifts and downshifts.
- **Delayed engagement:** A noticeable pause or hesitation when shifting from Park to Drive or Reverse, or between forward gears, often accompanied by a jolt once the gear engages.
- **Slipping:** The engine RPMs may rise without a corresponding increase in vehicle speed, indicating the transmission isn't fully engaging the gear, leading to a loss of power.
- **Shuddering or vibration:** A noticeable shake or vibration felt through the vehicle, particularly during gear changes or at specific speeds, which might indicate torque converter issues or internal wear.
- **Unintended downshifts or upshifts:** The transmission may shift gears unexpectedly, hold a gear for too long, or hunt between gears, disrupting smooth acceleration or deceleration.
- **Limp mode activation:** In severe cases, the transmission control module (TCM) may detect a serious fault and put the vehicle into
