Mercedes-Benz C230 shifter issue preventing shifting from drive to park and downshifting on Mercedes-Benz C230

Some Mercedes-Benz C230 owners report experiencing shifter issues that prevent shifting from drive to park and downshifting. These problems may stem from a defective shifter module, which can cause the shifter to become stuck in Park. Additionally, a malfunctioning brake light switch could contribute to this issue. Some owners also encounter connection problems between the ignition module and the shifter module. If the transmission is stuck in one gear and the Check Engine Light is illuminated, it may enter "limp home" mode, necessitating a visit to a Mercedes-Benz dealer. Furthermore, a malfunction in the transmission range sensor circuit (code P0705) can disrupt communication between the transmission and the engine control module, leading to inaccurate gear indications and shifting difficulties. While there is a shifter override feature available for manual shifting, identifying and resolving the underlying issue is crucial to ensure the transmission operates correctly, as a faulty shifter may result in the transmission being stuck in 2nd gear. Prompt attention to these concerns is essential for the proper functioning of the Mercedes-Benz C230's transmission.
