What are the reasons for the transmission warning light in Trumpchi vehicles?
3 Answers
The reasons for the transmission warning light in Trumpchi vehicles are: 1. Lack of automatic transmission fluid; 2. Failure to increase starting speed due to one-way clutch slippage; 3. Engine oil leakage; 4. Ignition coil or circuit malfunction. Taking the 2021 manual luxury edition Trumpchi GS4 as an example, its body dimensions are: 4545mm in length, 1856mm in width, 1700mm in height, with a wheelbase of 2680mm. The 2021 manual luxury edition Trumpchi GS4 features a MacPherson independent front suspension and a multi-link independent rear suspension. It is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 169PS, a maximum power of 124kW, and a maximum torque of 265Nm.
I've been driving a GAC car for almost ten years. The most common reason for the transmission warning light to come on is transmission fluid issues, such as low fluid level or dirty/contaminated fluid, which affects lubrication and cooling, triggering the system alarm. Sensor failures are also a major cause, especially when speed or position sensors malfunction, preventing signals from reaching the computer, which then lights up the warning. Control module faults are more troublesome, as incorrect commands from the computer can cause gear shifting to become jerky. Aging wiring harnesses or loose connectors may also lead to poor electrical contact. If the light comes on, it's advisable not to drive for too long to avoid exacerbating transmission wear and incurring higher repair costs. Promptly visit a repair shop to use a diagnostic tool to check the fault code, identify the root cause, and resolve it by changing the fluid or repairing the sensor. Regular maintenance and fluid checks are effective preventive measures.
Last month, while driving my GAC car, the transmission light suddenly came on, which gave me a scare. The reason could be insufficient oil or dirty oil. I looked it up and found out that this car's sensors are very sensitive, alerting even for minor issues. Also, faults in the computer control unit can trigger it—modern cars rely heavily on electronic systems, so any bug in the data line can cause the light to come on. Internal mechanical issues in the transmission, like clutch wear, can also trigger warnings. Don’t panic just because the light flashes. Safely pull over to check fluid levels or loose connections to avoid failure at high speeds. It’s best to connect your phone via Bluetooth to the car’s system to read the fault codes or visit a nearby 4S shop for a scan. Most of the time, an oil change or cleaning the sensors can reset it. Only drive again after handling it properly for peace of mind.
