Inspection and Verification
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
When internal wear/damage occurs in the transmission, metal particles, clutch plate material and band material can travel into the torque converter, the transmission fluid cooler tubes, the transmission fluid cooler, the transmission fluid heater (if equipped), and the cooler bypass valve (if equipped). These contaminants are a major cause of recurring transmission concerns. To prevent future concerns, remove these contaminants from the cooling system before placing the transmission back into use. Refer to the transmission fluid cooler backflushing and cleaning procedure.
- Verify the customer concern by operating the vehicle to duplicate the condition.
- 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 a transmission fluid leak is found in any of the transmission cooling components, install new components as necessary.
- If the cause is not visually evident, check for diagnostic trouble codes (DTCs). Refer to the DTC Chart.
- If no diagnostic trouble codes (DTCs) are present, verify the symptom and refer to the Symptom Chart.
