What is the reason for the car not moving when in D gear?
3 Answers
The reason why the car does not move when in D gear is due to problems with the shift valve, incomplete gear engagement preventing the oil passage from opening; failure of the transmission solenoid valve and electronic module; brake lock-up preventing the wheels from moving forward, with abnormal noises when accelerating. Solutions for transmission solenoid valve and electronic module failure: Short circuit or open circuit in the solenoid valve coil: replace the solenoid valve coil. Issues with the solenoid valve plug/socket: correct wiring errors, repair or replace the plug/socket. Problems with the solenoid valve spool: repair or replace the spool, or simply replace the entire solenoid valve. Solutions for inability to engage gears: Adjust the clutch at a repair shop; replace the clutch friction disc with a new one.
Encountering the issue of the car not moving when in D gear is quite common, in my opinion. Start by considering the simpler possibilities, such as insufficient or aged transmission fluid leading to poor lubrication, which might cause the clutch to jam after shifting. Next, check if the engine idle speed is too low or abnormal—if the RPM doesn't increase, the car naturally won't move. Additionally, a faulty gear position switch sensor might send incorrect signals to the transmission, causing the electronic control system to malfunction. I remember a friend's car had this issue once, and it turned out the brake was stuck, preventing the wheels from turning. In such cases, never force it—try turning off the engine and restarting once. If the problem persists, contact a repair shop immediately. Regular maintenance of the transmission and engine, along with periodic fluid changes, can prevent many issues. Safety always comes first.
As an experienced driver, I've encountered this situation a few times. Just after shifting to D gear, the car wouldn't move. Upon inspection, it might be a transmission issue - worn clutch plates or deteriorated fluid affecting power delivery. Sometimes it's an engine problem, like clogged fuel injectors causing insufficient power - the engine revs but the car doesn't move. Once I even forgot to release the handbrake, locking the wheels. For quick troubleshooting, check the dashboard for warning lights and gently press the accelerator to observe engine response. If unresolved, stop immediately and seek professional help - don't linger on dangerous roads. Regular vehicle checks during normal driving can prevent such issues.
