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

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

The transmission fault 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.

Yellow symbol warns of a problem with the gearbox.

If the car reports a transmission error, it is also possible that the sensors are malfunctioning. The first thing to do is to put the car in P, turn off the engine and apply the handbrake. Wait a moment 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 complicated 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 comes 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 and its lifespan will be significantly reduced. 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.
