1. Hydraulic Oil Circuit Control Exclusive to Toyota High-End Models
Tailored to the power output characteristics of Toyota's 2.0L/2.5L Dynamic Force engines (supporting a maximum torque of 250N·m), the valve body features an internal "matrix-type oil circuit + two-stage precision valve core" design. It can accurately distribute hydraulic oil to clutches and multiple planetary gear sets (for 6AT/8AT models) in real time. The built-in valve core (with a diameter tolerance of ≤ 0.003mm) dynamically adjusts the oil circuit pressure based on signals of engine speed, vehicle speed, and accelerator opening:
During low-speed startup, it maintains oil pressure stably between 0.9-1.3MPa, and reduces clutch engagement impact through the "buffer oil chamber + progressive valve core stroke" design;
During high-speed cruising (e.g., constant speed at 120km/h), it optimizes oil flow speed and pressure (oil pressure drops to 1.1-1.4MPa) to reduce energy consumption of the hydraulic system while ensuring no delay in power transmission, aligning with the "balance of smoothness and power" driving needs of Toyota mid-to-high-end models.
2. Intelligent Execution of Multi-Scenario Shift Logic
Deeply compatible with Toyota's new-generation Transmission Control Unit (TCU), it can real-time receive multi-dimensional driving scenario data—including frequent start-stop signals in urban congested roads, rapid acceleration signals for high-speed overtaking, high-load signals for mountain climbing, and special working condition signals for snow/sport modes. Through independent shift valve groups (8AT models are equipped with 8 sets of dedicated shift valves), it quickly switches oil circuit channels to achieve accurate shifting of 6/8 forward gears. Shift strategies are optimized for different scenarios:
In urban congestion, the shift interval between 1st-2nd gears and 2nd-3rd gears is shortened to within 0.3 seconds, with shift impact controlled at ≤ 35N;
During high-speed overtaking, the TCU can instruct the valve body to skip 1-2 gears (e.g., 4th-6th gears), with a shift response delay of ≤ 0.2 seconds to enhance power burst;
In snow mode, it reduces low-gear oil pressure (0.7-1.0MPa) to avoid wheel slipping, balancing safety and smoothness.
1. Precise Toyota Original Equipment Adaptation, Zero Installation Cost
As a Toyota original-spec valve body (part number 46313-23010), it is fully compatible with the transmission housing interfaces (e.g., U660E transmission matching Camry's A25A engine, U880E transmission matching RAV4's A25D engine) and wiring harness plug pin definitions (12-pin waterproof plug, meeting IP67 dustproof and waterproof standards) of specific Toyota mid-to-high-end models. No modification to installation dimensions or adjustment of circuit parameters is required. After installation, it can directly achieve "plug-and-play" communication with the original vehicle's TCU without additional computer programming or parameter calibration (the TCU can automatically identify original accessories and match preset parameters), significantly shortening maintenance and replacement working hours (regular replacement working hours ≤ 2 hours) and reducing installation adaptation costs and operational difficulty.
2. Toyota High-End Precision Manufacturing, Outstanding Durability
It adopts an aluminum alloy die-cast housing exclusive to Toyota high-end models (material: ADC14, tensile strength ≥ 260MPa, 13% higher than ordinary ADC12 material in strength). The surface is treated with "nanoceramic coating + electrophoresis" dual protection processes, and its corrosion resistance is 60% higher than that of ordinary valve bodies, capable of resisting oxidation and rust risks caused by long-term immersion in transmission oil (ATF WS oil service life ≥ 60,000 kilometers). The internal valve cores and valve sleeves are made of high-strength martensitic stainless steel (material: 4Cr13Mo, containing molybdenum to enhance wear resistance), and undergo "vacuum quenching + ultra-precision grinding" treatment, with a surface roughness of ≤ Ra0.02μm and a surface hardness of over HV1000. Their wear resistance is 40% higher than that of ordinary valve bodies. Under daily commuting scenarios (annual mileage of 20,000 kilometers), the service life of the valve body can reach more than 220,000 kilometers, reducing the frequency of later maintenance.
