Is the Flashing D Gear a Big Problem?
2 Answers
Whether the flashing gear is a big problem depends on two situations, as follows: 1. If the gear flashes but the vehicle can drive normally without any abnormal phenomena, then it is not a big problem. 2. If the gear flashes and the vehicle cannot shift gears, then it is a big problem. It is necessary to go to a professional auto repair shop in time to find out the cause as soon as possible. 3. Extended information: The flashing gear is usually because the driver did not press the brake when shifting gears, or did not press the brake fully before selecting the gear. Solution: Turn off the vehicle and restart it, and follow the standard operation when shifting gears. Press the brake fully before shifting gears.
I've been driving for decades and have encountered the D gear flashing situation quite often, which I consider quite serious. This usually indicates an issue with the transmission control system, such as a faulty gear position sensor or poor wiring contact, possibly due to abnormal oil pressure or module failure. If left unaddressed, the car might fail to shift gears, suddenly stall, which is especially dangerous on highways, and could even lead to complete transmission damage, resulting in expensive repairs. It's recommended to first check if the transmission fluid level is too low, then try restarting the car to see if the situation improves; but for safety's sake, it's best not to force driving and to promptly seek a professional technician to diagnose the fault codes with a diagnostic tool, ensuring safe and worry-free driving.
