What will happen if there is no transmission oil?
In addition to lubricating the mechanical parts inside the gearbox, gearbox oil also helps reduce wear and tear, dissipate heat, and ensure the gearbox operates more durably.
When a car's gearbox lacks oil, it can cause many serious problems, causing the gears and clutches in the gearbox to wear out quickly due to lack of lubrication. This directly affects the car's transmission performance, increasing the risk of vehicle damage.
Transmission fluid also plays a role in cooling the system. When the transmission lacks fluid, the internal temperature will increase rapidly, easily causing overheating and damaging important parts. For automatic transmissions, the fluid has the role of creating pressure and controlling the solenoid, the lack of fluid leads to difficulty in shifting gears.
In addition, lack of oil can cause the vehicle to vibrate during operation, reducing performance and affecting the life and performance of the gearbox.
Signs that your car's gearbox is lacking oil
- If there is a shaking sensation when shifting gears or while driving, or if the color of the transmission fluid turns dark brown or green and cloudy, the fluid may be damaged and needs to be replaced.
- Check for signs of rust in the gearbox oil. If you discover oil stains leaking from under the car, you should quickly take the car to a garage for inspection and repair.
- When the vehicle is in operation, when accelerating or shifting gears is difficult, it is also one of the signs that the vehicle's gearbox is lacking oil. At this time, you need to check the gearbox oil. On many modern vehicles, there will be an error indicator light or warning light on the dashboard to help users detect problems early.
- Burning or unusual odors may be due to your transmission overheating and lack of coolant.
