How to Fix Automatic Transmission Warning Light?
The best course of action is to let an expert mechanic diagnose the problem and repair your car. But if you have a good mechanical knowledge and you decide to try and fix the problem yourself, here are some steps to follow.
However, it’s important to remember that Automatic Transmission is a complex system and you should only attempt repairs if you’re confident in your abilities.
First start by checking your vehicle’s owner’s manual to see what the warning light means for your specific make and model. This will give you an idea of what might be wrong with your vehicle. Second you need to scan for OBD2 Trouble Code (DTC) using OBD2 scanner. Then you can take your code to the internet to find the cause of your fault and how to fix it. Once you know what the problem is and how to fix, you can purchase the necessary replacement parts and install them. Once everything is fixed, it’s time to erase the codes. Plug your scanner back in and erase the trouble code. You might need to confirm the changes. We recommend rescanning the engine to be sure they are gone. You will also see the automatic transmission warning light goes off.
If you can’t find the information you need online — or you don’t feel comfortable attempting repairs yourself—and the warning light on the car is still illuminated. We recommend getting to the service station to find out what the problem is or consider calling your local dealership for help.
