What does it mean when a car displays 'Check Transmission'?
1 Answers
A car displaying 'Check Transmission' indicates a malfunction in the transmission system. During prolonged use, due to frequent gear shifts, the components inside the transmission inevitably undergo wear and deformation, leading to issues such as difficulty in shifting gears, automatic gear disengagement, and unusual noises during operation, which affect its performance. Common transmission faults include: 1. Difficulty in shifting: When operating the gear lever, it feels strenuous to shift gears, and the gears cannot engage smoothly. A grinding noise may occur during shifting, and in severe cases, the gears may not engage at all. 2. Automatic gear disengagement: There are two common scenarios for automatic gear disengagement. One is when the gear jumps back to neutral upon slightly releasing the accelerator pedal while driving. The other occurs when climbing a hill under heavy load, where the gear immediately jumps back to neutral. In such cases, if attempting to re-engage the gear fails, it can easily lead to the vehicle rolling back, potentially causing serious accidents. 3. Transmission noise: Unusual noises from the transmission can occur in two situations. One is when the noise appears in neutral position, and the other is when the noise occurs during gear shifts while driving.
