Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid catch pan, funnel.
Safety Warnings: Disconnect the battery before starting work on electrical components and allow the engine to cool before working on the transmission.

2. Change Transmission Fluid

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Place a fluid catch pan under the transmission pan.
3. Remove the transmission pan bolts using a socket set.
4. Carefully lower the pan and drain the old fluid into the catch pan.
5. Replace the transmission filter if applicable.
6. Clean the pan and magnet (if equipped) to remove metal shavings.
7. Reinstall the pan using a new gasket and torque bolts to manufacturer specifications.

3. Inspect Torque Converter Solenoid

Sub-steps:
1. Locate the torque converter solenoid on the transmission.
2. Disconnect the wiring harness from the solenoid.
3. Use a multimeter to test the solenoid for proper resistance according to specifications.
4. If the solenoid is faulty, replace it with a new component.

4. Relearn Torque Converter

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and allow it to reach operating temperature.
3. Perform a torque converter relearning procedure using a scan tool as per manufacturer instructions, if necessary.
