What is the reason why the car cannot move after shifting gears?

Reasons why the car cannot move after shifting gears: Leakage in the automatic transmission oil pan, causing all hydraulic oil to leak out; The linkage or cable between the control handle and the manual valve rocker arm is loose, keeping the manual valve in the neutral or parking position; The oil pump inlet filter screen is clogged; Severe leakage in the main oil circuit; The oil pump is damaged. Here is additional information: 1. The car not moving after shifting gears is a comprehensive functional fault: (1) It involves the clutch, transmission, and drive axle. When diagnosing, the fault location should be determined first, and the condition of both wheels can be checked initially. (2) The diagnostic sequence generally starts from the drive wheels, moving forward through the rear axle to the drive shaft, then to the transmission, and finally to the clutch. If the drive shaft rotates but the car does not move forward, the fault lies in the rear axle. (3) Lift the rear axle and rotate one rear wheel. If the other rear wheel rotates in the opposite direction but the drive shaft does not rotate, it indicates that all rivets of the driven bevel gear are sheared off; If the other rear wheel does not rotate, check if the half-shaft is broken. 2. If the car does not move when starting in a certain gear and the drive shaft does not rotate, the fault is in the transmission: (1) Remove the transmission cover and inspect whether the transmission shift fork is broken or if the guide block fixing screws are loose. If the above checks are normal, proceed with the gear shifting test. (2) If the second shaft does not rotate in a certain gear, it means the half-round key of that gear is sheared off; If the second shaft rotates in direct drive but does not rotate in other gears, it indicates that the support bearings at both ends of the intermediate shaft are disassembled, causing the intermediate shaft to drop. (3) If the drive shaft does not rotate in any gear, the fault lies in the clutch. Check whether the clutch is severely slipping, whether all rivets of the driven disc spline hub and steel plate are sheared off, or whether the steel plate is broken.

I've been driving for over a decade and have encountered situations where the car doesn't move after shifting gears several times, usually due to clutch problems. For example, severe wear of the clutch disc or a burnt pressure plate can interrupt power transmission. When shifting gears, you feel the engine running but the car doesn't move, as if it's idling, which is a typical symptom. It could also be a transmission issue, such as stuck gears or damaged synchronizers in a manual transmission, or a malfunctioning valve body or hydraulic system leak in an automatic transmission. Don't overlook operating habits; not pressing the clutch pedal deep enough or forgetting to release the handbrake can also cause the car to stall. If you encounter this problem, you must stop in a safe place and check the clutch pedal travel. If it feels soft with no resistance, immediate repair is necessary. Otherwise, dragging the car can damage more components. It's advisable to find a reliable repair shop nearby for a thorough inspection.

Last time my car suddenly wouldn't move when shifting gears, and the inspection revealed it was an electronic system glitch. Modern cars rely on the ECU to control gear positions - incorrect sensor signals or main module failure can make the car think it's not in gear. It could also be a blown fuse cutting power to the electronic control unit, or wiring short circuits causing signal confusion. A loose gear selector connector can cause this too. I tried resetting the gears several times, and when that didn't work, I checked the fuse box - sure enough, a fuse had blown. I recommend keeping an OBD scanner handy; scanning for error codes will pinpoint the source. Remember to address it promptly to prevent electronic faults from developing into engine problems.

As a novice driver, I've encountered similar situations. When the car doesn't move after shifting gears, the reasons are often simple, such as the handbrake not being fully released or the P-gear position being stuck in an automatic transmission. First, confirm that the gear lever is pushed to the correct position, and for manual transmissions, ensure the clutch is fully depressed. Check the dashboard for any warning lights indicating brake issues. If it still doesn't work, try gently rocking the car back and forth to feel if the driveshaft or brakes are stuck. Avoid forcing the car to move to prevent greater damage. If the car remains immobile, it's best to seek help or call a repair shop for advice.
