What to do if the gearbox oil temperature is too high How to prevent the gearbox from overheating
1. Reasons and solutions for high temperature of automatic transmission
Reason 1 for high temperature: The engine and water temperature are too high, which affects the heat dissipation of the gearbox
Solution: Repair the engine.
High temperature reason 2: The radiator grille is blocked
Solution: Clean the Radiator
The third reason for high temperature: the gearbox clutch slips, which produces additional heat
Solution: Repair the coupler
High temperature reason 4: Insufficient flow of transmission cooling oil circuit
Solution: Repair the valve body or replace the oil pump
High temperature reason five: thermostat stuck
Solution: replace the thermostat
2. What to do if the gearbox oil temperature is too high
1. Regularly clean the water tank
Poor work of the heat dissipation system will cause many problems. The high-temperature transmission oil coming out of the transmission will return to the transmission without sufficient cooling.
The load on the torque converter can be very high because it doesn't get good heat dissipation.
The transmission oil will cause the viscosity change due to high heat, resulting in a low friction coefficient, which will cause the clutch to slip, so it is really important to clean the water tank regularly.
2. Purchase genuine gearbox oil that is guaranteed to match the gearbox
Automatic transmission manufacturing experts found that in the maintenance process of the transmission, there are often transmission faults caused by the use of fake oil or inferior oil that does not meet the quality standards.
In a faulty vehicle, the effect of poor quality oil on the transmission is devastating.
Generally speaking, low-quality oil has poor fluidity first, and cokes at high temperature, resulting in changes in the coupling speed of the clutch, resulting in a decrease in shift quality, and shift lag or shock.
If it hits, it will cause the combination to be out of joint, slip and even fail to drive, and in severe cases, the transmission will be scrapped.
3. Regularly replace the vehicle transmission oil
The gearbox and the engine also need to change the oil regularly. Whether it is the running-in of a new car or the normal wear and tear of an old car, some metal shavings will be worn off more or less. These metal shavings
Most will be intercepted by the filter element.
However, too fine metal shavings will still enter our automatic transmission along with the oil circuit, causing damage to some mechanical parts, so develop a good maintenance habit
It is a habit to change the gearbox oil regularly, so as to keep the car in better working condition
3. How to prevent the gearbox from overheating
1. Clean the gearbox frequently to avoid dirty gearbox due to the accumulation of oil dirt. Remember to check the cooling system of the gearbox on time.
2. As in the case of the engine, the gearbox should not be over-consumed either. If the gearbox oil temperature is overheated and an alarm is found, please pull over and stop immediately to dissipate heat.
3. When waiting for traffic lights or temporarily parking, it is best to switch the gearbox to N gear, do not hang D gear for a long time, and step on the brakes.
