1. Reasons and solutions for high temperature of automatic transmission
Cause of high temperature 1: The engine and water temperature are high, which affects the heat dissipation of the transmission
Solution : Repair the engine
High temperature reason two: The radiator grille is clogged
Solution: Clean the radiator
High temperature reason three: The gearbox clutch slips, resulting in Extra heat
Solution: Repair the coupler
High temperature reason four: Insufficient flow of the transmission cooling oil circuit
Solution: Repair the valve body or replace the oil pump
Cause 5 of high temperature: stuck thermostat
Solution: replace the thermostat
2. What to do if the gearbox oil temperature is too high
1. Clean the water tank regularly
Poor working of the cooling system will cause many problems. The high-temperature gearbox oil coming out of the gearbox returns to the gearbox without sufficient cooling. The load on the rotating torque converter will be very large because it does not receive good heat dissipation.
The transmission oil will change in viscosity due to high heat, resulting in a lower friction coefficient and causing clutch slippage, so it is really important to clean the water tank regularly.
2. Purchase genuine transmission oil that is guaranteed to match the transmission.
A survey by automatic transmission manufacturing experts found that during the maintenance process of the transmission, fake oil or incorrect oil is often used. In vehicles where inferior oil that meets quality standards causes transmission failure, the impact of inferior oil on the transmission is devastating.
Generally speaking, inferior oil has poor fluidity first and cokes at high temperatures, causing changes in the clutch’s coupling rate and causing a decline in shift quality, shift lag or impact, which in turn can cause coupling disengagement and slippage. It may even be impossible to drive, and in severe cases, the transmission may be scrapped.
3. Change the vehicle transmission oil regularly
The transmission oil, like the engine, also needs to be replaced regularly. Whether it is the running-in of a new car or the normal wear and tear of an old car, it will wear out more or less. Some metal shavings, most of which will be intercepted by the filter element.
However, too small metal shavings will still enter our automatic transmission along with the oil line and cause damage to some mechanical parts. Therefore, develop good maintenance habits and replace the transmission oil regularly. Only in this way can the car be kept in better working condition
3. How to prevent the gearbox temperature from being too high
1. Clean the gearbox frequently to avoid oil stains Accumulation causes the gearbox to be too dirty. Remember to check the gearbox dust regularly.Thermal system.
2. Just like the engine, the gearbox cannot consume too much. Once you find that the gearbox oil temperature is overheating and alarm, please pull over immediately to cool down.
3. When waiting for traffic lights or temporarily parking, it is best to switch the transmission to N gear. Do not leave D gear for a long time and apply the brakes.
