Solution

1. Preparation

Gather all necessary tools and components before starting the repair.
Ensure the vehicle is parked on a level surface, and secure it with wheel chocks.
Disconnect the battery to ensure safety while working on electrical components.

2. Remove Transmission Pan

Sub-steps:
- Use a socket set to remove the bolts securing the transmission pan.
- Carefully lower the pan and drain the transmission fluid into a suitable container.
- Clean the transmission pan and inspect for metal shavings or debris.

3. Inspect Torque Converter

Sub-steps:
- Remove the inspection cover (if applicable) to access the torque converter.
- Check for any signs of wear or damage on the torque converter housing and fluid coupling.
- Rotate the engine manually and observe the torque converter's rotation for any irregularities.

4. Replace Torque Converter (if necessary)

Sub-steps:
- Disconnect any electrical connectors and fluid lines attached to the torque converter.
- Remove the torque converter bolts and carefully pull the converter off the transmission input shaft.
- Install the new torque converter by aligning it with the input shaft and securing it with bolts to the specified torque (typically around 20-25 ft-lbs).
- Reattach fluid lines and connectors, ensuring a secure fit.

5. Reassemble and Refill Fluids

Sub-steps:
- Reinstall the transmission pan with a new gasket to prevent leaks.
- Refill the transmission with the correct type and amount of fluid as specified in the owner's manual.

6. Final Checks
