Why doesn't the car move after shifting into gear in an automatic transmission?

The car not moving could be due to reasons such as oil leakage, clogged filter screen, or oil pump damage. Here is the relevant information: 1. If a large amount of hydraulic oil sprays out from the pressure test hole, it indicates that the main oil circuit pressure is normal, and the fault lies in the input shaft, planetary gear set, or output shaft of the automatic transmission. The automatic transmission should be disassembled for inspection. 2. Check whether the linkage or cable between the automatic transmission control lever and the manual valve rocker arm is loose or detached. If it is loose or detached, it should be reinstalled and the position of the control lever readjusted. 3. If only a small amount of hydraulic oil flows out from the main oil circuit pressure test hole, with low or almost no oil pressure, the oil pan should be opened to check if the oil pump inlet filter screen is clogged. If there is no clogging, it indicates that the oil pump is damaged or there is a serious leak in the main oil circuit. The automatic transmission should be disassembled and inspected. 4. Remove the plug from the main oil circuit pressure test hole, start the engine, shift the control lever to the drive or reverse position, and check whether hydraulic oil flows out from the pressure test hole.
I've been driving for over a decade and often encounter situations where the car doesn't move after shifting into gear in an automatic transmission. Many fellow drivers have consulted me about this. The first thing to check is whether the engine is actually started. Sometimes the key is only turned halfway without ignition, and if the tachometer isn't moving, it means there's no power output. Then check if the gear is properly engaged - the D or R gear needs to be fully engaged. If the gear position sensor is faulty, the car won't receive the command. The brake system is crucial - with automatic transmissions, you must firmly press the brake to release the parking lock mechanism; the car won't move until the parking brake is fully released. Many people forget to release the electronic parking brake or don't release manual ones completely. There are also many transmission-related issues, like low fluid levels or internal clutch wear, which can prevent power transfer. I've also seen cases of electronic control module failures with warning lights showing on the dashboard. Regular maintenance should include checking transmission fluid levels and timely replacement to reduce risks. Don't delay - if the car doesn't move after shifting, don't force it; take it to a professional repair shop immediately.
