      Key Features:
      - Material: Case-hardened alloy steel (HRC 58-62) with ground helical teeth
      - Spline Design: Micro-polished internal splines for reduced wear against input shaft
      - Thrust Control: Integrated washer surface (critical for axial play adjustment)
      Failure Modes:
      - Spline Stripping: Causes gear spin (sudden 5-6 shift flare, P2716 codes)
      - Tooth Pitting: Fatigue from high-mileage overdrive use (whining noise)
      - Bearing Surface Wear: Alters planetary alignment (>0.15mm wear = replace)
      Critical Specs:
      1. Sun gear axial play: 0.10-0.25mm (requires selective thrust washers)
      2. Backlash with pinions: 0.07-0.13mm
      Pro Tip: Always replace sun gear and planetary carrier as matched set – mismatched wear patterns cause premature failure.
