Why does the car not move when shifted to D gear?

Check if the transmission fluid level is too low, whether the main oil pressure and gear oil pressure are normal, and then check if the gear switch signal is normal, if the wiring from the transmission computer to the shift solenoid valve is in good condition, and if the gear solenoid valve is functioning properly. If none of these are issues, it indicates a problem with the internal control system of the transmission, requiring disassembly of the transmission to inspect the internal components. Below is some related information: Automatic transmission: As the name suggests, it does not require the driver to manually shift gears; the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. Generally, automatic transmission cars have six gear positions, from top to bottom: P, R, N, D, S, L. Driving needs: Driving an automatic transmission car only requires the use of the parking gear P, reverse gear R, neutral gear N, and drive gear D to fully meet the needs of general driving. However, in some special driving environments, other functional gears may be needed. Therefore, if the correct control method is chosen, an automatic transmission car can perform better than a manual transmission.

I've also encountered situations where the car doesn't move when shifted to D gear before. There are usually several common causes to check. The most common issue is transmission problems, such as insufficient or old transmission fluid causing poor shifting. I recommend checking the fluid level and quality first. Another possibility could be a faulty driveshaft or torque converter, especially in older vehicles. Don't forget the electrical components - issues like a transmission control module malfunction or wiring short circuits can also prevent the car from moving. Sometimes, the parking brake might not be fully released; even if the handbrake appears loose, it could actually be stuck. Quickly shift to P gear, turn off the engine, and try again to see if there's any response. If warning lights appear on the dashboard, don't hesitate - get it checked by professionals immediately. Safety first.

Oh, it's really dangerous when the car doesn't move in D gear. From my driving experience, the first action is to safely pull over. First, check if the handbrake is fully released—this is often overlooked but easily fixed. If it still doesn't move, there might be an issue with the transmission's torque converter or hydraulic system; try switching to other gears like R or P to see if there's any response. Is the engine revving but the car not moving? It could be a problem with the drive chain or sensors. Avoid forcing any operations to prevent further damage. Finally, contact a repair shop promptly for diagnosis, and stay calm—don't panic.

Buddy, car not moving in D gear? Check these common causes first. If the handbrake is stuck, fix it; improper gear position or sensor failure could also be the issue. Transmission oil might be old and need replacement; a quick check on oil level and color can help. If nothing works, head to the repair shop, don't delay.
