Automatic transmission maintenance tips for changing transmission fluid
Many car enthusiasts like to learn some knowledge about car maintenance by themselves. If there is a small problem, they can solve it by themselves. It is not a problem to change the tire, change the oil, and filter the machine, but they do not understand some new things. must be enough. For example, the automatic transmission, which is becoming more and more common, cannot use the original simple method when replacing its transmission fluid.
In the eyes of most drivers, changing the transmission fluid (ie ATF fluid) in the automatic transmission is the same as changing the engine oil. Just find a place to put the old oil, tighten the oil drain plug, pour in the new oil, and check The oil dipstick is done, but it's not. Modern automobile automatic transmissions are highly sophisticated power transmission devices, mostly controlled by computers, equipped with many precision components: torque converters, sun gears, planetary gears and complex and small oil passages, etc., which pollute the material and temperature changes are very sensitive. Without the necessary maintenance, the automatic transmission will experience rough work and difficult shifting. According to statistics, 90% of automatic transmission failures are caused by the deterioration of transmission fluid pollution.
The traditional regular draining and filling of automatic transmission transmission fluid will leave more than 75% of the old transmission fluid in the cooling pipes of the torque converter and transmission. After the new automatic transmission transmission fluid is added, it will be immediately replaced by the old transmission fluid in the system. Contamination, sediment that is not drained can seriously affect the working performance of the system. In order to achieve the purpose of complete replacement, it is necessary to use the automatic transmission cleaning agent to completely remove the old fluid to ensure 100% replacement of the transmission fluid in the automatic transmission. In addition, protective agents and anti-leakage agents can also be added. Professional equipment is best used for these tasks. To be done.
Automatic transmission maintenance tips:
1. Every 50,000 kilometers of the car, connect the power supply of the device and the car, and use the matching connector to connect the device and the transmission cooling pipe. Then, when the engine is idling, add the automatic transmission cleaning agent, step on the brake with your foot, and replace each gear of the automatic transmission one by one to remove harmful substances, and then fully replace the automatic transmission fluid with the help of equipment.
2. Add an automatic transmission protective agent to the automatic transmission at a ratio of 5%. For the automatic transmission of an old car, it is best to add a bottle of automatic transmission leakage stopper to restore the aging of the transmission seal and prevent leakage.
3. Effect: The paint film and other deposits in the system can be completely discharged from the automatic transmission to avoid contamination of the new ATF fluid. Restore the elasticity of the automatic transmission oil seal and gasket, enhance the sealing performance, and prevent and stop the leakage of the automatic transmission. Improves the performance of ATF fluid and extends the life of ATF and automatic transmissions.
