Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Fluid Change

Sub-steps:
1. Remove the transmission fluid pan by loosening bolts (torque specifications: 10-12 ft-lbs).
2. Drain the old fluid into a suitable container.
3. Replace the transmission filter, ensuring proper alignment and sealing.
4. Reinstall the pan with a new gasket and torque to specifications.
5. Fill the transmission with new fluid (use Ford Mercon LV or equivalent) to the recommended level.

3. Torque Converter Replacement

Sub-steps:
1. Remove any components obstructing access to the torque converter (e.g., exhaust components, transmission supports).
2. Disconnect the transmission from the engine by removing the bell housing bolts (torque specifications: 30-35 ft-lbs).
3. Support the transmission with a jack and remove the torque converter from the input shaft.
4. Install the new torque converter, ensuring it is seated correctly on the input shaft.
5. Reconnect the transmission to the engine and torque the bell housing bolts to specifications.

4. System Check

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and let it idle, checking for fluid leaks.
3. Perform a road test to ensure proper operation of the torque converter and shifting.
