Brand Name:
FORD
Model Number:
10R80;10L80
Function: Alternates with friction plates to create precise clutch pack engagement, transmitting torque without slippage.
Key Features:
Material: High-carbon steel with hardened surfaces (60-65 HRC) for wear resistance.
Design: Laser-cut splines or notches for oil drainage and thermal stability.
Failure Modes:
Warping: Overheating (>300°F) causes distortion → clutch drag/shudder.
Scoring: Contaminated ATF grooves surfaces → reduced friction contact (P0776 codes).
Fatigue Cracks: Cyclic stress at spline edges → catastrophic pack failure.
