Identifying the Problem⁚
Before diving into troubleshooting, it’s crucial to understand what’s happening. Is the engine running smoothly? Are there any warning lights illuminated on the dashboard? Is there any unusual noise coming from the transmission? Observing these factors can provide valuable clues about the underlying problem.
Common Causes⁚
1. Low Transmission Fluid⁚
Automatic transmissions rely on fluid to lubricate and cool internal components. Insufficient fluid levels can lead to slippage, overheating, and ultimately, a transmission that won’t move.
2. Faulty Torque Converter⁚
The torque converter acts as a fluid coupling between the engine and transmission. If it malfunctions, the transmission may engage but not transfer power to the wheels.
3. Transmission Solenoid Problems⁚
Solenoids control the flow of transmission fluid to different parts of the transmission. If a solenoid fails, it can prevent the transmission from shifting properly.
4. Worn Clutch Plates⁚
Clutch plates within the transmission engage and disengage to transmit power. Worn or damaged plates can lead to slippage and an inability to move.
5. Transmission Control Module (TCM) Issues⁚
The TCM is the brain of the transmission, controlling various functions. A faulty TCM can result in incorrect shifting commands or a complete loss of transmission function.
Troubleshooting Steps⁚
1. Check Transmission Fluid Level⁚
With the engine running and the transmission in “Park” or “Neutral,” check the fluid level using the dipstick. If the level is low, add the correct type of transmission fluid.
2. Inspect for Leaks⁚
Check for any leaks around the transmission pan, cooler lines, or other components. If a leak is found, it needs to be addressed before further troubleshooting.
3. Test for Electrical Issues⁚
Use a multimeter to check for voltage at the transmission solenoids and the TCM. Any electrical issues need to be diagnosed and repaired.
4. Consult a Mechanic⁚
If the problem persists, it’s essential to seek professional help. A qualified mechanic can perform a thorough inspection, diagnose the root cause, and provide appropriate repairs.
Safety Considerations⁚
If your car won’t move, it’s crucial to prioritize safety. Park the vehicle in a safe location, turn off the engine, and engage the parking brake. Avoid attempting repairs yourself if you’re not familiar with automotive systems.
Conclusion⁚
When your car goes into gear but doesn’t move, it’s a sign of a potential transmission problem. By understanding the common causes and troubleshooting steps, you can take the first steps towards diagnosing the issue. Remember, if you’re not comfortable with automotive repairs, seek professional help from a qualified mechanic.
