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.

When the dashboard displays a 'Check Transmission' warning, I believe this issue should not be taken lightly, as it is often related to electronic faults in the transmission system. Common causes include aging sensors detecting abnormal signals or insufficient transmission fluid levels leading to unstable oil pressure. I once encountered a similar situation—after stopping to check, I found the dipstick showed low fluid levels, and the problem was alleviated after topping it up. However, if it's a mechanical issue like gear wear or a short circuit, a professional technician must diagnose it by using a computer to read the fault codes and determine the exact problem. Ignoring it while driving can easily cause the transmission to overheat and lock up, leading to sudden loss of power, which is extremely dangerous on highways. That's why I always pull over immediately to avoid delays in addressing the issue, significantly reducing repair costs and safety risks. Regular fluid changes and line inspections can prevent such troubles—always remember that safety comes first.

If the car suddenly prompts to check the transmission, I'll first perform some basic troubleshooting to reduce anxiety. Check the transmission fluid dipstick level - if it's below the minimum mark, top up with the correct specification fluid. Also inspect the engine bay for any oil leakage signs, which may indicate seal failure. Last time my car showed this warning, adding fluid and driving for a while solved it, costing less than 100 yuan. But if the issue persists, it could be a control module malfunction or internal component damage - don't force drive to avoid further damage. Simple DIY can save time and money, but complex cases require professional diagnostic tools. Regularly listen for abnormal noises like gear grinding during driving to detect and address issues early, protecting your vehicle's lifespan.

Seeing the transmission check warning always throws me off—it means there’s an issue with the transmission system. It could be triggered by low fluid levels or a faulty sensor. After consulting car-savvy friends, they advised against driving long distances and recommended heading to a repair shop ASAP. Minor fixes like topping up fluid may solve it, but major problems (e.g., a failed control unit) could cost thousands to fix. New drivers shouldn’t panic—just park safely to check the dipstick or visit a service center for help. Ignoring it risks sudden breakdowns, and roadside failures are a nightmare.
