TRANSWIN 6T30 6T40 6T45 Automatic Transmission Solenoid Valve Body TCU for Chevrolet Cruze


Product Description / Overview:


Eliminate severe shifting flares, limp-mode engagements, and communication fault codes with the premium TRANSWIN Automatic Transmission Solenoid Valve Body and TCU Assembly (TEHCM Module). Specially engineered for the Chevrolet Cruze and other GM-platform vehicles equipped with 6T30, 6T40, and 6T45 (Gen 1 / Gen 2) 6-speed automatic transmissions, this complete unit integrates the hydraulic control valve body, shifting solenoids, and the electronic Transmission Control Unit (TCU) into one seamless assembly. Manufactured using advanced automotive-grade testing components, it stabilizes line pressure and guarantees crisp, synchronized gear shifts.


Key Product Features:


  1. Fully Tested Solenoid Profiles: Every integrated fluid pressure switch and control solenoid is calibrated on premium dynamic bench testers to ensure exact OEM current-to-pressure response curves.
  2. Upgraded Heavy-Duty Circuit Board: The embedded TCM features heavy-duty internal wire bonding and premium substrate gel sealing to resist extreme thermal cycling and fluid contamination under heavy operation.
  3. Precision Valve Bore Refurbishment: The hydraulic valve body section incorporates high-grade anodized valves to prevent pressure leakage across critical regulator circuits, restoring factory-level fuel economy and acceleration.

  • Global Wholesale Supply: We offer highly competitive factory-direct tier pricing, secure anti-static protective packaging to safeguard sensitive microelectronics, and low MOQs for global trade distributors.

⚠️ Rebuilder Technical Insight 


GM 6T30/6T40 transmissions are highly sensitive to fluid cleanliness. When replacing this TEHCM valve body assembly, a complete transmission flush is mandatory. Metal debris from worn input drums or failed wave plates will instantly clog the sensitive magnetic fluid pressure switches on the new module, causing premature comebacks.

Note: This unit requires electronic programming/re-flashing (using GM SPS or a compatible J2534 passthru tool) matching the target vehicle's exact VIN before it can operate on the car.
