WARNING: This page is about a different variant/trim than selected.
| Symptom | Possible Sources | Action |
|---|---|---|
| TCC does not apply | TCC solenoid filter screen blocked | INSTALL a new TCC solenoid. REFER to: Solenoid . |
| TCC solenoid mechanically stuck OFF | INSTALL a new TCC solenoid. REFER to: Solenoid . | |
| TCC regulator valve stuck OFF | DISASSEMBLE, CLEAN and INSPECT the TCC regulator valve. If bore or valve is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body . | |
| TCC control valve stuck OFF | INSTALL a new pump assembly. REFER to: Transmission . | |
| TCC APPLY hydraulic circuit blocked or leaking | DISASSEMBLE and INSPECT the transmission, main control valve body and pump assembly passages for debris/blockage/leaks. CLEAN or REPLACE components as necessary. REFER to: Main Control Valve Body . REFER to: Transmission . | |
| TCC friction material worn or damaged. | INSTALL a new torque converter. REFER to: Transmission - 1.5L EcoBoost (118kW/160PS) - I4 . REFER to: Transmission - 2.0L EcoBoost (184kW/250PS) - MI4 . REFER to: Transmission - 2.5L Duratec (125kW/170PS) . | |
| TCC always applied/stalls vehicle | TCC solenoid mechanically stuck ON | INSTALL a new TCC solenoid. REFER to: Solenoid . |
| TCC regulator valve stuck ON | DISASSEMBLE, CLEAN and INSPECT the TCC regulator valve. If bore or valve is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body . | |
| TCC control valve stuck ON | INSTALL a new pump assembly. REFER to: Transmission . | |
| TCC RELEASE hydraulic circuit blocked or leaking | DISASSEMBLE and INSPECT the transmission, main control valve body and pump assembly passages for debris/blockage/leaks. CLEAN or REPLACE components as necessary. REFER to: Main Control Valve Body . REFER to: Transmission . | |
| TCC welded or damaged. | INSTALL a new torque converter. REFER to: Transmission - 1.5L EcoBoost (118kW/160PS) - I4 . REFER to: Transmission - 2.0L EcoBoost (184kW/250PS) - MI4 . REFER to: Transmission - 2.5L Duratec (125kW/170PS) . | |
| TCC cycles, shudders or chatters | Incorrect Transmission Strategy programmed into the PCM | REFER to: Transmission Strategy Download . |
| TCC solenoid filter or seal damaged at TCC solenoid | INSTALL a new TCC solenoid. REFER to: Solenoid . | |
| TCC solenoid mechanically sticking | INSTALL a new TCC solenoid. REFER to: Solenoid . | |
| TCC regulator valve, springs, clips loose, stuck, binding, missing, misassembled | DISASSEMBLE, CLEAN and INSPECT the TCC regulator valve. If bore or valve is damaged, INSTALL a new main control valve body. REFER to: Main Control Valve Body . | |
| TCC control valve, springs, clips loose, stuck, binding, missing, misassembled | INSTALL a new pump assembly. REFER to: Transmission . | |
| TCC RELEASE/TCC APPLY hydraulic circuit blocked or leaking | DISASSEMBLE and INSPECT the transmission, main control valve body and pump assembly passages for debris/blockage/leaks. CLEAN or REPLACE components as necessary. REFER to: Main Control Valve Body . REFER to: Transmission . | |
| TCC cycling/shudder/chatter | Verify the TCC is causing the concern. Attempt to duplicate event while commanding the PID TCC_OSC OFF. If the concern cannot be duplicated while the TCC is commanded off the TCC may be worn or damaged. REFER to: Transmission - 1.5L EcoBoost (118kW/160PS) - I4 . REFER to: Transmission - 2.0L EcoBoost (184kW/250PS) - MI4 . REFER to: Transmission - 2.5L Duratec (125kW/170PS) . | |
