      Key Components:
      - Lepelletier Design: 1 Ravigneaux + 1 simple planetary set for compact 8-speed ratios
      - Hardened Gears: Case-hardened steel (HRC 60+) with ground tooth profiles
      - Needle Bearings: Low-friction support for planetary pinions
      Failure Modes:
      - Sun Gear Spline Wear: Causes 3-5-7 gear slippage (P2714 codes)
      - Pinion Bearing Failure: Results in gear whine (check endplay <0.15mm)
      - Carrier Cracks: Fatigue near thrust washers (metal debris in pan)
      Critical Specs:
      1. Sun gear axial play: 0.10-0.25mm
      2. Pinion gear backlash: 0.05-0.12mm
      Pro Tip: Always replace planetary thrust washers during rebuilds – worn washers alter gear alignment.
