Product Description
        • Function: Engages low/reverse gears by actuating multi-plate clutch packs in planetary gearset applications (common in 4WD/RWD transmissions).

          Key Components:

          • Drum Body: Hardened aluminum or steel with precision splines for clutch plate engagement

          • Integrated Piston: Hydraulically actuated with reinforced seals for high-pressure apply (60-100 psi)

          • Bleed Channels: Prevent clutch drag during release

          Failure Modes:

          • Spline Wear: Causes incomplete clutch engagement (slippage in low gear)

          • Piston Seal Leaks: Results in delayed reverse engagement

          • Drum Cracks: Thermal stress near weld points (sudden loss of drive)

          Critical Checks:

          1. Measure drum runout (<0.08mm)

          2. Verify clutch clearance (1.0-1.8mm typical)

          3. Inspect for blueing (overheating evidence)

          Pro Tip: Always replace drum seals during rebuilds – reused seals have 80% higher failure rate.
