For C clutch operation, REFER to: C Clutch .

C clutch

Condition	Possible Sources	Action
C clutch does not apply	SSC is mechanically stuck off	INSTALL a new solenoid. REFER to: Solenoid .
	C clutch control valve stuck off	DISASSEMBLE, CLEAN and INSPECT the clutch control valve. If the bore or valve is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body .
	C CL CONTR, hydraulic circuit blocked/leaking	DISASSEMBLE and INSPECT the main control valve body and separator plate passages for debris/blockage. CLEAN as necessary. REFER to: Main Control Valve Body .
	C clutch piston seals	INSPECT the components for wear and damage. CLEAN and/or INSTALL new components as necessary. REFER to: TRANSMISSION
	C clutch hub/reaction sun gear	The C clutch hub and the B clutch drum are the same component. If diagnostics indicate both C clutch and B clutch failures, INSPECT the components for wear and damage. INSTALL new components as necessary. REFER to: TRANSMISSION
	C clutch friction plates	INSPECT the components for wear and damage. INSTALL new components as necessary. REFER to: TRANSMISSION
C clutch always applied	SSC mechanically stuck	INSTALL a new solenoid. REFER to: Solenoid .
	C clutch regulator valve or C clutch latch valve stuck on	DISASSEMBLE, CLEAN and INSPECT the regulator valve. If the bore or valve is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body .
	C CL CONTR, hydraulic circuit cross leaks	DISASSEMBLE and INSPECT the main control valve body and separator plate passages for debris/blockage. CLEAN as necessary. REFER to: Main Control Valve Body .
	C clutch hub, clutch and planetary carrier, No. 4 ring gear	INSPECT the components for wear and damage. INSTALL new components as necessary. REFER to: TRANSMISSION
