Is the Issue of Automatic Transmission Not Moving When Engaged Serious?

[VanAnnie]

Automatic transmission not moving when engaged is caused by leakage in the automatic transmission oil pan, looseness in the linkage or cable between the manual valve operating handle and the rocker arm, or blockage in the oil pump intake filter screen. Leakage in the automatic transmission oil pan: If only a small amount of hydraulic oil flows out from the pressure measurement hole of the main oil circuit, and the oil pressure is very low or almost nonexistent, it indicates leakage in the automatic transmission oil pan, causing the vehicle not to move. Open the oil pan and check if the oil pump intake filter screen is blocked. If there is no blockage, it means the oil pump is damaged or there is severe leakage in the main oil circuit, and the automatic transmission should be disassembled. Looseness in the linkage or cable between the manual valve operating handle and the rocker arm: If the linkage or cable between the manual valve operating handle and the rocker arm is loose, the manual valve remains in the neutral or parking position. If it is loose, it should be reassembled, and the position of the operating lever should be readjusted. Blockage in the oil pump intake filter screen: If there is some oil pressure in the main oil circuit when starting a cold engine, but the oil pressure drops significantly after the engine warms up, it indicates excessive wear in the oil pump, and the oil pump should be replaced.

I've been driving for years, and it's truly nerve-wracking when an automatic transmission won't move after shifting gears. I remember one time at a highway entrance when I shifted to D but the car wouldn't budge—fortunately, I managed to pull over quickly, or the consequences could have been dire. This issue is absolutely serious because it can leave you stranded in dangerous positions, like at intersections or in the middle of busy roads, increasing the risk of rear-end collisions. Even if no accident occurs, calling a tow truck still costs time and money. If it happens on a slope, there's even a risk of the car rolling, endangering yourself and others. My advice is to immediately turn off the engine and seek professional help in any situation—don't try to tough it out, safety comes first. You can check if the parking brake is released as a routine measure, but this is often a deeper mechanical issue that requires prompt repair.

I usually drive an automatic transmission car for commuting, and it's really annoying when the car won't move after shifting gears. For example, when I'm in a hurry to go to work or pick up my kids, the car just stays put in the garage or by the roadside, completely disrupting my schedule and possibly causing delays. This issue is quite serious, not only affecting daily life arrangements but also potentially leading to engine overheating or damage to other components. Most of the time, the problem lies with the transmission, such as insufficient fluid or a malfunctioning control system, which isn't something you can fix on your own. It's important to address it promptly to prevent a minor issue from becoming a major hassle. In the city, it's a bit more manageable, but in the suburbs, you're left stranded, so don't delay. Regular maintenance can reduce the chances of this happening, but when it does occur, it's advisable to call for roadside assistance first.

I've worked on many cars, and an automatic transmission not moving when shifted usually indicates a major issue. It could be a transmission fluid leak, or a faulty sensor or torque converter. This is serious because if the car doesn't move, it's essentially useless and requires professional diagnosis. Forcing it to start might burn out more components, making repairs even more expensive. Check the fluid level or warning lights as soon as possible. Don't hesitate—call a mechanic.
