12V Clutch Control Solenoid Valve – For Volvo & Mack I-Shift/mDRIVE Systems


一、Core Part Identification

Critical Note: Confirm your truck’s  solenoid valve part number matches any of the above to ensure seamless fit and functionality.

2. Key Electrical & Functional Specs

二、Vehicle Fitment


三、Key Product Advantages
  1. 12V System Compatibility: 12V electrical architecture, delivering stable current draw and reliable valve actuation (prevents electrical overload or underperformance).
  2. Broad Part Number Coverage: Replaces 10+ interchange part numbers, eliminating the need to source different solenoids for varying Volvo/Mack model years.
  3. Durable Construction:
    • Valve body: High-strength metal (resists pressure and corrosion from hydraulic fluids).
    • Electrical coil: Insulated copper (withstands under-truck temperature fluctuations and vibration, reducing coil burnout risk).

四、Installation & Usage Tips

  1. Pre-Install Checks:
    • Confirm the solenoid’s connector matches your truck’s wiring harness (even if part numbers align).
    • Flush the transmission’s hydraulic/pneumatic lines (if recommended) to remove debris that could clog the new valve.
  2. Post-Install Testing: After installation, test the transmission’s shifting (idle and driving) to ensure smooth clutch engagement—address any irregularities immediately.
  3. Voltage Verification: Use a multimeter to confirm the truck’s electrical supply to the solenoid is 12V DC (fluctuations outside this range may indicate a separate electrical issue).
