A Comprehensive Overview of the Automatic Transmission System

The automatic transmission system is an essential component of modern vehicles, ensuring smooth and efficient power delivery to the wheels. It is responsible for automatically changing gear ratios as the vehicle's speed and load conditions vary, eliminating the need for manual gear shifting. At Shenghai Auto Parts, we understand the importance of a well-functioning transmission system and offer a wide range of high-quality parts to keep your vehicle running flawlessly.

The Key Components of the Automatic Transmission System

1. Transmission Fluid

Transmission fluid acts as the lifeblood of the automatic transmission system. It not only lubricates the various moving parts but also facilitates the transfer of power within the system. At Shenghai Auto Parts, we provide a selection of premium transmission fluids that are specifically engineered to meet the requirements of different vehicle models. Our fluids offer optimal protection against wear, heat, and oxidation, ensuring the longevity and performance of your transmission system.

2. Torque Converter

The torque converter plays a crucial role in the automatic transmission system. It is responsible for transmitting power from the engine to the transmission, allowing the wheels to rotate. Shenghai Auto Parts offers a range of high-quality torque converters, designed to deliver optimal performance and efficiency. Our torque converters are engineered to withstand the demands of everyday driving, providing a smooth transfer of power and enhanced fuel economy.

3. Planetary Gear Set

The planetary gear set is a complex arrangement of gears that enables the automatic shifting of gears. It consists of multiple gear sets that work together to provide different gear ratios. This allows the vehicle to operate effectively in various speed and load conditions. At Shenghai Auto Parts, we offer a variety of planetary gear sets, manufactured with precision to ensure optimal gear engagement and minimal power loss.

4. Valve Body

The valve body is the control center of the automatic transmission system. It directs the hydraulic fluid flow to engage specific gears and control the shifting process. Shenghai Auto Parts supplies high-quality valve bodies that are engineered to exact specifications, ensuring smooth gear transitions and precise shifting performance. Our valve bodies are designed to provide maximum reliability and durability, helping your transmission system operate at its best.

5. Solenoids

Solenoids are electro-hydraulic valves that control the flow of transmission fluid within the system. They play a crucial role in gear shifting and various other functions of the automatic transmission. At Shenghai Auto Parts, we offer a wide range of solenoids that are manufactured to the highest standards, ensuring consistent and reliable performance. Our solenoids are designed to withstand harsh conditions and provide efficient transmission operation.

6. Clutches and Bands

Clutches and bands are responsible for engaging and disengaging the gears within the automatic transmission system. As the name suggests, clutches rely on friction to transfer power between rotating components, while bands wrap around specific components to lock them in place. Shenghai Auto Parts supplies top-quality clutches and bands that are designed for durability and precise engagement, ensuring smooth gear transitions and overall system reliability.

7. Sensors and Control Module

Modern automatic transmission systems are equipped with sensors and a control module that constantly monitor various parameters and adjust the system accordingly. These sensors provide crucial information, such as vehicle speed, throttle position, and fluid temperature, allowing the control module to make precise gear changes. At Shenghai Auto Parts, we offer a range of sensors and control modules that are built to exact specifications, ensuring accurate readings and reliable system performance.


In conclusion, the automatic transmission system is a complex and vital component of every vehicle. At Shenghai Auto Parts, we take pride in offering an extensive range of high-quality auto parts and supplies, specifically designed to cater to the needs of your automatic transmission system.
