1. Does the transmission oil need to be replaced regularly?
Transmission oil is an oil that keeps the gear system clean. It can ensure the normal operation of the gearbox and extend the transmission time. The life of the device plays a role. Generally, the transmission oil needs to be replaced regularly. If the automobile transmission oil is not replaced for a long time, it will lead to the following hidden dangers:
1. The transmission oil will deteriorate and volatilize if it works at high speed and high temperature for a long time. , thereby aggravating the wear of mechanical parts, and in serious cases damaging the internal parts of the gearbox.
2. If the transmission oil is not changed for a long time, the car will be unable to start when it is cold.
3. The vehicle is prone to slight skidding during driving.
4. If the transmission oil is not replaced for a long time, the transmission oil will become thicker and easily block the transmission radiator, causing the transmission oil temperature to be too high and aggravating wear and tear.
2. How often should the transmission oil be changed?
The replacement cycle of transmission oil is not fixed and needs to be determined according to the actual situation:
1. Under normal circumstances, the automatic transmission must be replaced every 2 years or every 40,000 kilometers traveled. gearbox oil. For manual transmissions, it is generally recommended to change the transmission oil every three years or every 100,000 kilometers driven, because the internal structure of the manual transmission is much simpler than that of the automatic transmission.
2. If the vehicle shifts smoothly and the gearbox noise does not change much, you do not need to change gears. If the vehicle seems jerky when shifting gears, especially after the driving speed exceeds 100 kilometers, the gearbox noise increases significantly. You should consider whether the transmission oil should be replaced.
3. In addition, the car model will also affect the frequency of changing the transmission oil. For example, for Nissan models, most of them recommend changing it every 40,000 to 80,000 kilometers. If you usually drive a lot on high speeds, it is recommended that you change it every 40,000 kilometers. You have to change it every kilometer.
3. What are the consequences of not changing the automatic transmission oil?
1. There will be weakness when starting, and the vehicle will often slip during driving.
2. The oil in the transmission granules, blocks the oil circuit, and strains the valve body, which will directly affect the system oil pressure and power transmission, causing slow response of the transmission and shifting shock.
3. It will not only increase the fuel consumption of the vehicle and slow down the starting speed of the vehicle, but also aggravate the wear of mechanical parts, and in severe cases damage the internal parts of the gearbox, shortening the life of the vehicle.Life becomes shorter.
In addition to the conventional lubrication, cleaning and cooling functions, transmission oil also plays the role of transmitting engine power in the hydraulic torque converter, and at the same time transmits working pressure in the hydraulic working system, so that The shift actuator performs the shift operation correctly.
