Car Will Not Go Into Gear When Engine Running
Problem Description
When you try to shift the gear lever into any gear while the engine is running, it does not move. The gear lever may feel stuck or stiff, or it may move slightly but not engage the gear.
Causes
There are several possible causes for this problem:
- Clutch problem: The clutch is a mechanical device that connects the engine to the transmission. If the clutch is not fully disengaging, it can prevent the gear lever from moving into gear.
- Transmission problem: A problem with the transmission itself can also prevent the gear lever from moving into gear. This could be caused by a worn or damaged gear, a problem with the shift linkage, or a low fluid level.
- Driveline problem: A problem with the driveline, such as a worn or damaged driveshaft or universal joint, can also cause the gear lever to stick.
- Electrical problem: An electrical problem, such as a faulty neutral safety switch, can also prevent the gear lever from moving into gear.
Diagnosis
To diagnose the problem, a mechanic will typically start by checking the clutch. They will do this by depressing the clutch pedal and feeling for any resistance. If the clutch is not fully disengaging, it will need to be repaired or replaced.
If the clutch is not the problem, the mechanic will then check the transmission. They will do this by shifting the gear lever through all of the gears and feeling for any grinding or other noises. They will also check the fluid level and condition.
If the transmission is not the problem, the mechanic will then check the driveline. They will do this by inspecting the driveshaft and universal joints for any signs of wear or damage.
If the driveline is not the problem, the mechanic will then check the electrical system. They will do this by checking the neutral safety switch and other electrical components.
Repair
The repair for this problem will depend on the underlying cause. If the clutch is the problem, it will need to be repaired or replaced. If the transmission is the problem, it may need to be rebuilt or replaced. If the driveline is the problem, the worn or damaged components will need to be replaced. If the electrical system is the problem, the faulty components will need to be repaired or replaced.
Prevention
There are a few things you can do to help prevent this problem from occurring in the future:
- Drive in the correct gear: Always drive in the correct gear for the speed and conditions. Avoid lugging the engine or over-revving it.
- Do not shift gears too quickly: When shifting gears, take your time and allow the transmission to fully engage each gear.
- Get regular maintenance: Regular maintenance can help to prevent problems with the clutch, transmission, and other components that can lead to this problem.
If you are experiencing this problem, it is important to have it diagnosed and repaired by a qualified mechanic as soon as possible. Ignoring this problem can lead to further damage to your vehicle.
