Gearbox error light - a detail that Vietnamese drivers rarely pay attention to

The transmission fault warning light usually comes on when there are 3 problems: temperature, pressure and internal fluid level.

The transmission check engine light is usually represented by a gear icon with an exclamation point in the middle. The icon is yellow or red depending on the vehicle model.

The yellow symbol warns of a problem with the transmission.

If the car reports a transmission error, it is also possible that the sensors are malfunctioning. The first thing to do is put the car in park, turn off the engine and apply the handbrake. Wait a while and then start the car again. If the light goes out, the problem is solved, but if the light stays on, the transmission is really having a problem.

If this happens, the driver should have the car checked as soon as possible to avoid future expenses. Because the gearbox is a sophisticated and complex part, replacement and repair are often very expensive.

Usually, this warning does not mean that the transmission is damaged, but rather a reminder of a harmful factor. The light is on when the transmission is usually experiencing one of three problems: oil temperature, oil pressure, and internal oil level. To determine the exact cause, the repairman must use professional diagnostic equipment.

If the driver is indifferent and continues to use the car for a long time, the gearbox will quickly deteriorate, significantly reducing its lifespan. Some expensive car models also have the ability to limit the rpm or speed so that the gearbox is not under too much pressure. On the BMW car forum, an owner of a BMW 328i E36 deliberately drove when the gearbox warning light was on. He could not accelerate normally and the rpm did not exceed 2,000 rpm even though he had pressed the accelerator pedal.
