What to Do When the Gear Exclamation Mark Appears on the Dashboard?
1 Answers
Dashboard gear exclamation mark is the transmission system warning light. TCU, which stands for Transmission Control Unit, refers to the automatic transmission control unit. This function enables automatic transmission control, making driving simpler. The appearance of this symbol indicates an abnormality in the transmission. If this light comes on while driving, you should stop driving immediately and seek professional assistance at a 4S shop as soon as possible. Generally, only cars equipped with automatic transmissions have this light. Cars with manual transmissions do not have this light because manual transmissions lack computers and sensors, making them less prone to malfunctions.
