A car that won’t start can be a frustrating experience‚ especially if you’re dealing with an automatic transmission. The issue could be as simple as a dead battery or as complex as a transmission problem. This guide will walk you through the common causes and steps to troubleshoot your automatic transmission car that won’t start.
Check the Basics
- Battery⁚ Start by checking the battery. Make sure the terminals are clean and tight‚ and use a voltmeter to check the battery voltage. If it’s below 12 volts‚ you need a new battery.
- Starter⁚ If the battery is good‚ check the starter. You can try tapping on the starter with a hammer (be careful!) to see if it starts. If not‚ the starter may be faulty and needs to be replaced.
- Fuel⁚ Ensure you have enough fuel in the tank. A low fuel level can sometimes prevent the car from starting.
Transmission-Specific Checks
- Transmission Fluid⁚ Check the transmission fluid level. If it’s low‚ it could be the culprit. However‚ be careful not to overfill the transmission. Refer to your owner’s manual for the correct level.
- Transmission Solenoid⁚ A faulty transmission solenoid can prevent the transmission from engaging. This could be due to a broken solenoid or a problem with the wiring. A mechanic can diagnose and repair this issue.
- Torque Converter⁚ A faulty torque converter can prevent the engine from transferring power to the wheels. This is a more complex issue that requires professional diagnosis and repair.
Other Potential Issues
- Fuse Box⁚ Check the fuse box for blown fuses related to the transmission system.
- Computer Module⁚ A faulty transmission control module (TCM) can prevent the transmission from functioning properly. This requires professional diagnosis and repair.
When to Seek Professional Help
If you’ve checked the basics and still can’t figure out why your car won’t start‚ it’s time to seek professional help. A qualified mechanic can diagnose the problem and provide a solution. Don’t attempt to repair complex transmission issues yourself as this could worsen the problem.
Remember‚ safety is paramount. If you suspect a transmission issue‚ it’s best to have the car towed to a repair shop. Attempting to drive a car with a faulty transmission can be dangerous.
