Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid pump.
Ensure the vehicle is on a flat surface and securely lifted with jack stands.
Disconnect the negative battery terminal.

2. Check and Change Transmission Fluid

Sub-steps:
1. Remove the transmission fluid pan using the socket set.
2. Drain the old fluid into a suitable container.
3. Inspect the pan for metal shavings or debris; clean if necessary.
4. Replace the filter if applicable.
5. Reinstall the pan with a new gasket, tightening bolts to manufacturer specifications (consult service manual for torque values).
6. Refill with the recommended transmission fluid through the dipstick tube, ensuring proper fluid level.

3. Inspect and Replace Torque Converter

Sub-steps:
1. Remove the transmission from the engine following the manufacturer’s service manual instructions.
2. Disconnect and remove the torque converter from the transmission.
3. Inspect the torque converter for any signs of wear or damage (cracks, broken components).
4. Install a new torque converter, ensuring proper alignment and securing it in place.
5. Reattach the transmission to the engine, ensuring that all bolts are tightened to the specified torque.

4. Electrical Inspection

Sub-steps:
1. Reconnect all electrical connectors to the torque converter solenoid and associated wiring.
2. Test each connector for continuity using a multimeter.
3. If any wiring is damaged, repair or replace as necessary.
