Function: GM-sourced 6-speed FWD/AWD automatic (MH8 code) for 2.4L/3.2L applications (torque capacity 350Nm).

Rebuild Enhancements:

• Upgraded Clutches: High-energy 3-5-R pack (friction count increased from 5 to 6)

• Revised Valve Body: Sonnax boost valves prevent line pressure loss (P0871 mitigation)

• Bearing Kits: Oversized rollers for input shaft support

Failure Points:

1. TCC Shudder: Worn converter clutch material (P0741)

2. Solenoid D Failure: Causes 3-4 shift flare (P0756)

3. Case Porosity: Oil pump suction leaks (low pressure at idle)

Critical Service:

• Fluid: Dexron VI only (7.2L capacity)

• Adaptations Reset: Tech2/MDI required post-install

• Cooler Flush: Mandatory to remove debris

Pro Tip: Verify pump prime – dry starts destroy rebuilt units in <1km.
