Product Description

- - - Function: Transmits engine torque to the planetary gearset via engaged clutch plates (typically 1st-3rd/4th gears).
      
      Key Components:
      - Input Shaft: Hardened steel with precision-ground splines (connects to torque converter)
      - Clutch Drum: Aluminum/steel hybrid with laser-welded piston channel
      - Integrated Piston: High-pressure seals (Vitron or HNBR) for rapid apply
      Failure Modes:
      - Spline Wear: Causes clutch drag (delayed engagement, P0776 codes)
      - Drum Warpage: Overheating distorts sealing surface (>0.1mm runout = replace)
      - Seal Extrusion: Contaminated ATF degrades seals → pressure loss
      Critical Checks:
      1. Measure shaft endplay (<0.3mm)
      2. Verify drum concentricity (dial indicator test)
      3. Inspect piston bore for scoring
      Pro Tip: Pre-soak new clutch plates in ATF for 30 mins – dry plates cause initial shift flare.
