Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is on a level surface and safely supported with jack stands.

2. Fluid Change

Sub-steps:
1. Remove the transmission fluid pan using a socket set.
2. Drain the old transmission fluid into a suitable container.
3. Replace the transmission filter if applicable.
4. Reinstall the pan with a new gasket and torque the bolts to manufacturer specifications.
5. Refill the transmission with the recommended type and quantity of transmission fluid.

3. Torque Converter Replacement

Sub-steps:
1. Remove the drive shaft and any components obstructing access to the torque converter.
2. Unbolt the torque converter from the flex plate using a socket set.
3. Remove the torque converter from the transmission input shaft.
4. Install the new torque converter by aligning it properly with the input shaft, ensuring it seats fully into the transmission.
5. Reattach the flex plate to the torque converter and torque the bolts to specified values.
6. Reassemble any components that were removed.

4. Final Checks

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and check for any leaks around the torque converter and transmission.
3. Test the vehicle to ensure the symptoms have been resolved.
