1. Low transmission fluid: If the transmission fluid is low, it can cause the transmission to slip and not engage properly. Check the transmission fluid level and add more if necessary.
2. Dirty transmission fluid: Dirty transmission fluid can also cause the transmission to slip. Have the transmission fluid changed if it's dirty.
3. Faulty transmission: If the transmission is damaged or faulty, it may not be able to engage properly. This could be due to a worn-out clutch, a broken gear, or a faulty solenoid.
4. Faulty shift linkage: The shift linkage is what connects the gear selector to the transmission. If the shift linkage is damaged or disconnected, it can prevent the transmission from engaging properly.
5. Faulty transmission control module (TCM): The TCM is the computer that controls the transmission. If the TCM is faulty, it can send the wrong signals to the transmission, causing it to not engage properly.
6. Faulty Torque converter: The torque converter is a component that connects the engine to the transmission. If it is faulty, it cannot transfer power properly, causing the car to not move.
If you're not sure what the problem is, it's best to have your car inspected by a qualified mechanic. They can diagnose the problem and recommend the best course of action.
