1.Precise Hydraulic Pressure Regulation
Controls the flow and pressure of transmission fluid to key components (clutches, planetary gear sets) via 6–8 integrated solenoid valves. It adjusts pressure in real time based on TCU commands: For example, during hard acceleration, it increases clutch pressure to prevent slippage; during low-speed crawling, it reduces pressure to enable smooth, low-jerk gear changes.
2.Clutch Engagement/Disengagement Coordination
Manages the hydraulic oil supply to multi-plate clutches (for DCT/AT) to control engagement speed and clamping force. For dual-clutch transmissions (DCT), it synchronizes the pressure of the “oncoming” and “disengaging” clutches—shortening shift time to ≤0.3 seconds while avoiding gear grinding or harshness.
3.Torque Converter Lockup Control
Regulates the hydraulic pressure supplied to the torque converter’s lockup clutch. At high speeds (>90km/h), it fully engages the clutch to eliminate fluid slip, improving fuel efficiency by 8–10%; during low-speed acceleration, it partially disengages the clutch to leverage the torque converter’s multiplication effect, enhancing low-end power.
4.Fluid Direction & Flow Distribution
Distributes transmission fluid to lubrication, cooling, and control circuits via integrated channels. It ensures critical components (gears, bearings) receive sufficient lubrication to reduce wear, while directing excess fluid to the transmission cooler to maintain optimal operating temperature (80–110°C)—preventing overheating-related performance degradation.
1.High Compatibility with Advanced Powertrains
Tailored for modern automatic transmission systems (6AT/7DCT), 8891125096 strictly adheres to original equipment (OE) standards for electrical communication protocols (CAN FD), hydraulic interface dimensions, and mounting positions. It seamlessly integrates with the vehicle’s transmission control unit (TCU) and engine control unit (ECU), eliminating issues like signal latency, hydraulic leakage, or mismatched connectors that often occur with universal components—ensuring synergy with high-torque powertrains (up to 350N·m).
2.Superior Durability for Intensive Use
①.Housing:
Adopts die-cast magnesium alloy (30% lighter than aluminum) with a ceramic coating, resisting engine compartment temperatures up to 180°C and vibration (≤40g)—suitable for frequent high-speed driving or heavy-load scenarios.
②.Internal Components:
Electronic chips use automotive-grade MCU with a wide temperature range (-40°C to 125°C); hydraulic valves feature diamond-like carbon (DLC)-coated cores, reducing wear by 50% compared to standard steel valves.
③.Reliability:
Mean Time Between Failures (MTBF) exceeds 15,000 hours, meeting the durability requirements of premium vehicle brands.
3.Next-Gen Precision Control Performance
①.Electronic Control:
Equipped with a 32-bit high-speed microcontroller (processing speed 80MHz), it achieves a response time of ≤25ms to TCU commands, ensuring rapid adjustment of gear shift timing and clutch pressure.
②.Hydraulic Control:
Maintains hydraulic pressure fluctuation within ±1%, with ultra-precision valve machining (tolerance ≤0.005mm) to avoid pressure spikes—minimizing shift shock (≤0.08g) for a smoother driving experience.
4.Energy Efficiency Optimized for Modern Vehicles
Features an intelligent power management system: In standby mode, it operates at a low current (≤60mA at 12V DC), reducing parasitic power draw from the vehicle’s electrical system. For hybrid transmissions, it coordinates with the hybrid control unit (HCU) to adjust hydraulic/electronic control logic during regenerative braking, improving energy recovery efficiency by 12% compared to traditional components.
5.Comprehensive Multi-Layer Protection
①.Electrical Protection:
Integrates over-voltage (18V max), reverse-polarity, and ESD (electrostatic discharge) protection (compliant with IEC 61000-4-2) to shield against electrical anomalies.
②.Thermal Protection:
Dual-temperature sensors monitor component and transmission fluid temperatures; if temperatures exceed 185°C, it triggers a thermal shutdown to prevent damage.
③.Hydraulic Protection:
Built-in pressure relief valves (for hydraulic versions) automatically release excess pressure (≥3.8MPa), safeguarding hoses and seals from burst risks.
6.Cost-Effective Premium Alternative
Priced 20–25% lower than genuine OE parts from premium brands while maintaining equivalent performance and quality. Its long service life and low maintenance needs reduce total cost of ownership for vehicle owners and fleet operators, making it ideal for high-end transmission maintenance.
