Symptom Chart
For C clutch operation, REFER to: 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 . | |
