Applicable vehicle type: For VO LVO

The transmission valve body serves as the control core of an automatic transmission. Without it, automatic gear shifting functionality ceases entirely. All operations revolve around power transmission, gearshift control, and system protection, making it essential for the proper operation of automatic vehicles:

✅ Primary Function: Precise hydraulic control for automated gear shifting

Through the opening and closing of internal precision spools and valves, it regulates hydraulic fluid flow to the transmission's clutches, brakes, and planetary gear sets. This controls friction plate engagement/disengagement to achieve automatic shifting between 1st to 9th gears and reverse. It intelligently adjusts shift timing based on vehicle speed, engine load, and throttle position, balancing power delivery with fuel economy.

✅ Core Function: Precise hydraulic pressure regulation for smooth power delivery

Integrated primary and secondary pressure control valves precisely regulate transmission oil pump output within the 0.5-8MPa rated range. This prevents hydraulic line rupture from excessive pressure and power transmission slippage from insufficient pressure, ensuring jerk-free gear changes and seamless power transitions.

✅ Supplementary Functions: Multi-functional system management safeguards the transmission

• Controls torque converter lock-up and disengagement to enhance transmission efficiency at high speeds and reduce fuel consumption;
• Regulates hydraulic oil circulation pathways to provide cooling and lubrication for internal gears, bearings, and friction plates, preventing high-temperature wear;
• Incorporates built-in overflow and pressure relief protection, automatically venting excess pressure to prevent hydraulic system failures from escalating;
• Receives electrical signals from the Transmission Control Unit (TCU) to achieve electro-hydraulic coordination, adapting to driving modes such as Sport, Economy, and Comfort.
