Symptom Chart: Transaxle - Transmission Cooling
Diagnostics in this service information assume a certain skill level and knowledge of Ford-specific diagnostic practices. Refer to DIAGNOSTIC METHODS for information regarding Ford-specific diagnostic practices.
| Condition | Possible Sources | Actions |
|---|---|---|
| Transaxle overheating | Clogged transmission fluid cooler or transmission fluid cooler tubes | INSPECT the transmission fluid cooler, transmission fluid cooler tubes and transmission fluid thermal bypass valve for damage or plugging. INSTALL new components as necessary. REFER to Transmission Fluid Cooler Tubes - 3.5L Ti-VCT . |
| Bent or crushed transmission fluid cooler tubes | INSPECT the transmission fluid cooler, transmission fluid cooler tubes and transmission fluid thermal bypass valve for damage or plugging. INSTALL new components as necessary. REFER to Transmission Fluid Cooler Tubes - 3.5L Ti-VCT . | |
| Transmission fluid thermal bypass valve stuck closed | For the 3.5L Ti-VCT REPLACE the thermal bypass valve. REFER to Thermal Bypass Valve - 3.5L Ti-VCT . For the 2.0L GTDI REPLACE the transmission fluid cooler tubes and the thermal bypass valve as an assembly. REFER to Transmission Fluid Cooler Tubes - 2.0L GTDI . | |
| System leaks | Check the transmission fluid cooler tubes and fittings between the transmission and the transmission fluid cooler. If a leak cannot be stopped by tightening the transmission fluid cooler tube nut, install new parts. When Motorcraft® MERCON® LV Automatic Transmission Fluid is found leaking between the case and the transmission fluid cooler line fitting, check for missing or damaged O-ring, then tighten the fitting to specification. | |
| Are there transaxle DTCs | REFER to PINPOINT TEST G: TFT SENSOR : P0710, P0711, P0712, P0713, P1711, P1783. | |
| Vibration - a high frequency (20-80 Hz) that is felt through the seat or gear shifter and changes with engine speed. | Transmission fluid cooler tubes grounded | INSPECT the transmission fluid cooler tubes for damage or grounding. INSTALL new components as necessary. REFER to Transmission Fluid Cooler Tubes - 3.5L Ti-VCT . |
