1. Central Control of Hydraulic System
As the "command center" of the transmission, it accurately controls the flow direction, pressure, and flow rate of hydraulic oil through built - in components such as pressure regulating valves and clutch control valves. When the vehicle is running, the valve body receives signals from the electronic control unit, drives the solenoid valve to switch the oil circuit, realizes the accurate engagement and disengagement of the clutch and brake band, and completes the core operation of gear shifting.
2. Execution of Intelligent Shifting Logic
Based on real - time data of vehicle speed and engine load, it automatically adjusts the transmission ratio. When driving at low speeds, it quickly completes downshifting to provide sufficient torque; when driving at high speeds, it smoothly upshifts to reduce the engine speed. This not only ensures the power output during starting and climbing but also takes into account the fuel efficiency during high - speed cruising, achieving a balance between power and economy.
3. System Protection and Status Management
The built - in hydraulic pressure monitoring mechanism can maintain the stable system pressure in real time, avoiding shifting impact or component damage caused by abnormal pressure. At the same time, through the optimized oil passage design, it helps the circulation of transmission oil, provides lubrication and heat dissipation support for precision components such as the valve plate and spool, reduces mechanical wear, and extends the overall service life of the transmission.
1. Precise Fit for Specific Vehicles, Strong Installation Compatibility
As a dedicated valve body assembly for the CVT transmission of the older Toyota Prado 4000, it is designed in accordance with original factory - consistent dimensional standards. The oil passage layout of the valve plate and the spool stroke perfectly match the hydraulic system of the original vehicle's transmission, allowing direct installation without additional modifications. Its matching relationship has been verified through actual vehicle adaptation, enabling accurate connection with the original vehicle's torque converter and planetary gear transmission system, and solving problems such as installation misalignment and oil circuit incompatibility that are common with non - adaptive valve bodies.
2. Precision Manufacturing Process, Excellent Operational Stability
High - precision CNC machining technology is used to manufacture internal oil passages and valve components, with channel tolerances controlled at the micrometer level to ensure the accurate flow path of hydraulic oil. The core components are made of high - quality alloy materials that are resistant to high pressure and high temperature, which can withstand the continuous pressure and temperature fluctuations during the operation of the transmission. This effectively reduces the risk of spool wear and valve body deformation, extending the service life by more than 30% compared with ordinary valve bodies.
3. Intelligent Adaptation to Working Conditions, Optimized Driving Experience
It integrates high - precision speed valves and throttle valves, which can real - time capture key parameters such as engine load and vehicle speed, and dynamically adjust the shifting logic. Under complex road conditions, it can achieve millisecond - level response for upshifting and downshifting actions, significantly reducing the shifting jitter. During high - speed cruising, it optimizes the hydraulic pressure regulation to reduce power transmission loss, helping to improve the fuel economy of the vehicle.
