Key Components:
Drum Material: Forged aluminum with hardened steel splines (OEM 33404-30030)
Integrated Piston: Triple-lip seal design for high-pressure stability (90-120 psi apply)
Bearing Surfaces: Precision-ground for input shaft support
Failure Modes:
Spline Rounding: Causes clutch slippage (P0770 codes)
Seal Extrusion: ATF degradation leads to pressure loss (delayed engagement)
Thrust Washer Wear: Alters axial clearance → clutch drag
Critical Specs:

Clutch pack clearance: 0.8-1.2mm
Shaft endplay: 0.1-0.3mm
Pro Tip: Replace both drum and input shaft if splines show polishing – indicates mutual wear
