Inspection and Verification

  1. Verify the customer concern by operating the vehicle to duplicate the condition.
  2. If the inspection reveals an obvious concern(s) that can be readily identified, repair as necessary.
  3. Install new components if a transmission fluid leak is found in any of the transmission cooling components.
  4. If the cause is not visually evident, verify the symptom and refer to the «SYMPTOM CHART»(ref-635256-S16174323942014070200000) .
SymptomPossible SourcesAction
Transmission overheatingClogged transmission fluid cooler or transmission fluid cooler tubes Bent or crushed transmission fluid cooler tubesINSPECT 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) .
Active grille shutter stuck in closed positionREFER to: ACTIVE GRILLE SHUTTER
System leaksINSPECT transmission fluid cooler and transmission fluid cooler tubes for leaks. SERVICE as required.
Internal transmission concernsREFER to: AUTOMATIC TRANSMISSION - HYBRID ELECTRIC VEHICLE (HEV) .

SYMPTOM DESCRIPTION

  1. Verify the customer concern.
  2. Visually inspect for obvious signs of mechanical or electrical damage.
  3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
  4. If the cause is not visually evident, verify the symptom and refer to the «SYMPTOM CHART»(ref-635256-S16174323942014070200000) .
