Mercedes-Benz C230 gearshift failure due to fluid spill requiring complete gearshift assembly replacement on Mercedes-Benz C230

Some Mercedes-Benz C230 owners report experiencing gearshift failures due to fluid spills, which can necessitate the replacement of the Shift Gate Module. This issue often arises when liquids spill onto the gear shifter, causing shorting in the Shift Gate module and resulting in the vehicle getting stuck in gear. Prompt repairs are crucial to prevent serious transmission problems, and regular maintenance is recommended to avoid issues such as erratic shifting, gear being stuck in Park, and entering Limp Mode. In instances of transmission failure symptoms, owners are advised to check the transmission fluid levels and condition, as contaminated or insufficient fluid can severely impact the transmission's ability to shift smoothly. Additionally, other common causes of gearshift issues reported by owners include a defective brake light switch, low voltage or dead battery, spilled liquid on the shifter assembly, and faults in the engine control unit (ECU) or transmission control unit (TCU).
