Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Transmission jack
Funnel for fluid refill

2. Fluid Change

Sub-steps:
1. Locate the transmission drain plug and remove it to drain the fluid completely.
2. Inspect the drained fluid for contamination; if it is dark or burnt, it may indicate further issues.
3. Replace the transmission filter if applicable by removing the pan bolts and gently lowering the pan.
4. Install a new filter and reattach the pan using a new gasket.
5. Refill the transmission with the manufacturer's recommended fluid using a funnel.

3. Torque Converter Inspection

Sub-steps:
1. Remove any necessary components to access the torque converter (e.g., transmission cover).
2. Inspect the torque converter for signs of wear or damage.
3. Test the lock-up clutch function by applying power while observing engagement.
4. If faulty, replace the torque converter by unbolting it from the flywheel and removing it from the transmission.

4. Reassembly and Final Checks

Sub-steps:
1. Reinstall any components that were removed to access the torque converter.
2. Reconnect the battery and ensure all electrical connections are secure.
3. Start the vehicle and check for leaks around the transmission and torque converter areas.
