Why Doesn't an Automatic Transmission Car Move When in Gear?
1 Answers
Automatic transmission cars may fail to move when in gear due to the following reasons: 1. Gear lock or incomplete braking when parking, directly shifting into P gear, causing gear braking. 2. Leakage in the automatic transmission oil pan. 3. Loosening of the linkage or cable between the control lever and the manual valve rocker arm, keeping the manual valve in neutral or park position. 4. Clogging of the oil pump inlet filter screen. 5. Severe leakage in the main oil circuit. 6. Damage to the oil pump. 7. If the entire vehicle cannot be powered on, the automatic transmission enters self-protection mode and will not shift; gear unlocking can be performed by pressing the black button above the transmission P gear.
