Solution

1. Preparation

Gather tools and materials needed for the repair.
Disconnect the battery to prevent electrical shorts.

2. Change Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Remove the transmission pan using a socket set, and drain the old fluid into a container.
3. Replace the transmission filter if applicable; clean the pan and replace the gasket.
4. Reinstall the transmission pan and tighten bolts to the manufacturer's torque specifications (usually around 10-12 Nm).
5. Fill the transmission with fresh, manufacturer-approved transmission fluid using a funnel.

3. Inspect and Replace Torque Converter (if necessary)

Sub-steps:
1. If the fluid change did not resolve the issue, remove the transmission from the vehicle (refer to service manual for specific removal instructions).
2. Disconnect the torque converter from the transmission by removing the bolts securing it.
3. Replace the torque converter with a new or remanufactured unit.
4. Reattach the transmission and torque converter, ensuring all bolts are properly torqued.

4. Final Checks

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and allow it to reach operating temperature.
3. Verify there are no leaks and check fluid levels again, adding fluid if necessary.
