Why Can't I Shift to D Gear?
2 Answers
Why Can't I Shift to D Gear? The reasons include the following situations: 1. Internal failure of the gear shift lever assembly. If there is an internal failure in the gear shift lever assembly, it cannot shift to D gear, and the gear shift lever assembly needs to be repaired. 2. The gear is locked. You can perform a gear unlock. 3. When parking, the car was not fully braked, and P gear was directly engaged, causing gear braking instead of brake braking. Repair the solenoid valve and brake switch. 4. The entire vehicle cannot be powered on, and the automatic transmission is in self-protection mode, which also prevents shifting. If the entire vehicle is not powered on and the transmission is in self-protection mode, you can press the black button above the P gear of the transmission to unlock it.
Yesterday at the shop, we encountered a vehicle that couldn't shift into Drive. Inspection revealed an issue with the gearshift lever assembly. Nowadays, automatic gearshift levers all have a cable underneath connecting to the transmission. After prolonged use, the cable either gets stuck or snaps entirely. Another common issue is a faulty transmission control module, often accompanied by a persistent check engine light on the dashboard. If the car won't shift when cold but works fine after warming up, it's likely time for a transmission fluid change. In such cases, it's best to tow it to the repair shop rather than forcing it to drive - having a technician read the trouble codes is the most reliable approach. By the way, after inserting the key, don't rush to start the engine; try shifting through all gear positions a few times first. Sometimes this can resolve mechanical sticking issues.
