View Product Description

- - - Function: Engages overdrive (O/D) gear by applying hydraulic pressure to clutch pack in planetary transmissions (e.g., 4L60E, A340E).
      
      Key Features:
      - Material: Billet aluminum with micro-polished bore (surface finish Ra ≤0.8μm)
      - Seal Design: Dual-lipped HNBR or Viton for high-temp stability (>250°F)
      - Bleed Circuit: Quick-release channels prevent clutch drag
      Failure Modes:
      - Seal Roll-Over: Improper installation causes pressure leaks (O/D slippage)
      - Bore Scoring: Contaminants jam piston (delayed O/D engagement)
      - Fatigue Cracks: Stress fractures near apply lugs (sudden O/D loss)
      Critical Specs:
      1. Piston-to-bore clearance: 0.03-0.07mm
      2. Apply pressure: 55-85 psi (varies by transmission)
      Pro Tip: Lubricate seals with petroleum-free grease during assembly – petroleum degrades rubber.
