09G TF-60SN Automatic Transmission K1 Drum Clutch Assembly
The K1 drum clutch assembly is a critical torque transfer component in dual-clutch (DCT/DSG) transmissions. Key analysis:
-
Function – Controls odd gears (1st/3rd/5th/7th) via multi-plate clutch pack engagement in the concentric input shaft design.
-
Construction – High-strength steel drum housing with precision-machined splines, integrated piston, and wave springs for smooth apply/release.
-
Failure Modes – Drum cracks (fatigue), clutch plate glazing, or piston seal leaks causing slippage, shift hesitation, or DTCs (e.g., P17BF).
-
Critical Checks – Measure clutch pack clearance (0.5-1.2mm typical), inspect drum runout (>0.1mm indicates replacement).
