Direct Clutch

Condition	Possible Sources	Action
Direct (3, 5, R) clutch does not apply	SSB Solenoid filter blocked	CLEAN or INSTALL a new solenoid. Refer to: Solenoid .
	SSB is mechanically stuck OFF	INSTALL a new solenoid. Refer to: Solenoid .
	Direct (3, 5, R) clutch regulator valve stuck OFF	DISASSEMBLE, CLEAN and INSPECT the direct (3, 5, R) clutch regulator valve. Refer to: Main Control Valve Body . If bore or valve is damaged, INSTALL a new main control valve body.
	SSB SIG, C35R, C35R SUP hydraulic circuits 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 .

	Direct (3, 5, R) clutch friction plates	DISASSEMBLE and INSPECT the direct (3, 5, R) clutch friction and steel plates. Measure clutch pack clearance. INSTALL new components as necessary. Refer to: Transmission .
	Direct (3, 5, R) clutch piston return spring	INSPECT the return spring for damage. INSTALL new components as necessary. Refer to: Transmission .
Direct (3, 5, R) clutch delayed/soft/slipping apply	Incorrect Transmission Strategy programmed into PCM	Remove SSB and record solenoid band number. Refer to: Solenoid . Using the scan tool, verify the correct band number is stored in the PCM. If bands numbers do not match, INSTALL a new SSB with correct band number.
	SSB solenoid filter partially blocked or restricted	INSTALL a new solenoid. Refer to: Solenoid .
	SSB mechanically sticking	INSTALL a new solenoid. Refer to: Solenoid .
