What Causes a Car to Fail to Shift Gears After Driving Through Water?

[McAthena]

Car failing to shift gears after driving through water is due to the clutch being stuck after getting wet, resulting in incomplete disengagement. Below are other reasons why a car may fail to shift gears: P Gear Lock Solenoid Valve Malfunction: To prevent accidentally shifting into other gears when starting the vehicle, there is a P gear solenoid valve. The solenoid valve needs to receive a signal from the brake pedal to release. These two components are interconnected; if either one malfunctions, it will prevent the gear lever from being pushed out of P gear into other gears. Gear Lever Assembly Internal Malfunction: Worn gears inside the gear lever cause the lever to get stuck, making it difficult to move forward or backward, resulting in an inability to shift gears or difficulty in shifting. Incomplete Clutch Disengagement: This may be due to a malfunctioning clutch disc or clutch pressure plate, requiring replacement of the clutch three-piece set: friction disc, pressure plate, and release bearing.
