Inspection and Verification
- Verify the customer concern by operating the vehicle to duplicate the condition.
- If the inspection reveals an obvious concern(s) that can be readily identified, repair as necessary.
- Install new components if a transmission fluid leak is found in any of the transmission cooling components.
- If the cause is not visually evident, verify the symptom and refer to the «SYMPTOM CHART»(ref-539217-S06651859902013040100000) .
Symptom Chart
| Symptom | Possible Sources | Action |
| Transmission overheating | Clogged transmission fluid cooler or transmission fluid cooler tubes Bent or crushed transmission fluid cooler tubes | INSPECT the transmission fluid cooler and the transmission fluid cooler tubes damage or plugging. INSTALL new components as necessary. REFER to: TRANSMISSION FLUID COOLER TUBES - PLUG-IN HYBRID ELECTRIC VEHICLE (PHEV) (307-02 Transmission Cooling, Removal and Installation). |
| Active grille shutter stuck in closed position | REFER to: ACTIVE GRILLE SHUTTER (501-02 Front End Body Panels, Diagnosis and Testing). |
| System leaks | INSPECT transmission fluid cooler and transmission fluid cooler tubes for leaks. SERVICE as required. |
| Internal transmission concerns | REFER to: AUTOMATIC TRANSMISSION - HYBRID ELECTRIC VEHICLE (HEV) (307-01 Automatic Transmission - Vehicles With: Automatic Transmission - HF35, Diagnosis and Testing). |
- Verify the customer concern.
- Visually inspect for obvious signs of mechanical or electrical damage.
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
- If the cause is not visually evident, verify the symptom and refer to the «SYMPTOM CHART»(ref-539217-S06651859902013040100000) .
