An automatic transmission is a device that can automatically shift gears based on engine speed, as opposed to a manual transmission. There are three common types of automatic transmissions in cars: hydraulic automatic transmission (abbreviated as AT), continuously variable transmission (abbreviated as CVT), and electronically controlled mechanical automatic transmission (abbreviated as AMT).
The automatic transmission is a device that can automatically shift gears based on engine speed, as opposed to a manual transmission. There are three common types of automatic transmissions in cars: hydraulic automatic transmission (AT), continuously variable transmission (CVT), and electronically controlled mechanical automatic transmission (AMT).
In the eyes of most drivers, changing the transmission fluid (ATF) in an automatic transmission is similar to changing the engine oil; just find a place to drain the old oil, tighten the drain plug, pour in the new oil, and check the dipstick, and it's done. However, this is not the case. Modern automatic transmissions are highly precise power transmission devices, mostly controlled by computers, equipped with many precise components: torque converters, sun gears, planet gears, and complex, tiny oil passages, all of which are very sensitive to contaminants and temperature changes. Without necessary maintenance, automatic transmissions can experience rough operation and difficulty shifting. Statistics show that 90% of automatic transmission failures are caused by contamination and degradation of the transmission fluid.
Automatic transmission maintenance tips:
1. Every 50,000 kilometers, connect the device to the car's power supply and use the matching connector to connect the device to the transmission cooling line. Then, while the engine is idling, add an automatic transmission cleaner, press the brake pedal, and sequentially change through all the gears of the automatic transmission to remove harmful substances, then use the device to completely replace the automatic transmission fluid.
2. Add an automatic transmission protector to the automatic transmission at a ratio of 5%. For older cars, it is best to add a bottle of automatic transmission stop leak agent to restore the aging seals of the transmission and prevent leaks.
3. Effect: It can completely expel deposits such as paint film from the system, avoiding contamination of the new ATF. Restore the elasticity of the automatic transmission oil seal, enhance sealing performance, and prevent and stop leaks in the automatic transmission. Improve the performance of the ATF and extend the lifespan of both the ATF and the automatic transmission.
Cars equipped with automatic transmissions do not have a clutch, fundamentally avoiding unexpected engine stalls due to improper operation. However, some automatic models may still stall unexpectedly due to mechanical failure. In such cases, if there are no issues ahead, you can restart without stopping.
The specific method is to quickly push the gear lever into neutral (N), turn the ignition switch to the start (START) position, and after successfully restarting, quickly pull the gear lever back to D to drive normally. If multiple attempts fail to restart the engine, it indicates a more serious fault, and you should decisively pull over for repairs.
Using this method requires familiarity with the vehicle's operation. If too much force is used to push the gear lever directly into reverse (R), it can cause significant damage to the transmission. Additionally, some vehicles have ignition switches that prevent a second start; you must first turn it back to the off position to restart, but be careful not to lock the steering wheel. Furthermore, after the engine stalls, the brakes and power steering will also fail, requiring more force to control the vehicle.
All of this is well understood in normal circumstances, but in emergencies, it can be chaotic. Therefore, if you are a novice, it is best to safely pull the car over to the side of the road. Remember: at any time, vehicles equipped with automatic transmissions should not use reverse towing to start.
The company is based on "specialization and innovation" (specialization, boutique, characteristic, novel), focusing on the research and development, design, production and sales of automobile automatic transmission clutch hub and parts. The company has invested nearly 0.5 billion yuan and introduced nearly 100 sets (sets) of professional production and supporting equipment from the world. It has become one of the enterprises in the domestic gear hub industry with excellent equipment, complete configuration, strong R & D capability, numerous developed products and large production capacity, and has formed an annual production capacity of 4 million pieces (sets).
The company broke the situation that the core components of the automatic transmission gear hub have been monopolized by European and American multinational enterprises, boosted the localization process of automatic transmissions of domestic independent brand automobile enterprises, and led the new era of "intelligent manufacturing in China" of the core components of the automatic transmission gear hub.
