- - - Typical Faults:
      1. Spline Wear at Shaft-Drum Interface
        
        Symptom: Delayed forward engagement (P0776 codes)
        
        Cause: Micro-movement from torque reversals
      2. Drum Warpage
        
        Symptom: Harsh 1-2 shifts or clutch drag
        
        Trigger: Overheating (>300°F) distorts sealing surface
      3. Piston Seal Extrusion
        
        Symptom: Pressure loss in forward gears only
        
        Root Cause: Contaminated ATF degrading seal material
      Critical Measurements:
      - Shaft Runout: >0.05mm requires replacement
      - Drum-to-Piston Clearance: 0.10-0.15mm (use feeler gauge)
      - Seal Groove Wear: >0.2mm depth = rebuild
      Pro Tip: Always replace shaft and drum as matched set – mismatched splines accelerate wear.
