Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid funnel, and safety glasses.
Ensure the vehicle is on a level surface and engage the parking brake.

2. Remove the Transmission Fluid

Sub-steps:
1. Locate the transmission drain pan and place a suitable container underneath.
2. Remove the drain plug and allow the fluid to drain completely.
3. Replace the drain plug and torque to manufacturer specifications (typically around 10-15 ft-lbs).

3. Disconnect the Torque Converter

Sub-steps:
1. Remove the transmission access cover to expose the torque converter.
2. Disconnect the electrical connectors from the torque converter.
3. Unbolt the torque converter from the flex plate (typically 3-4 bolts).
4. Carefully slide the torque converter away from the transmission.

4. Install the New Torque Converter

Sub-steps:
1. Position the new torque converter in place and align it with the transmission input shaft.
2. Ensure it is seated correctly into the pump.
3. Bolt the torque converter to the flex plate and torque to specifications.

5. Refill Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick tube and insert a funnel.
2. Pour new transmission fluid (as specified in the owner’s manual) into the funnel.
3. Start the engine and let it idle while checking fluid levels; add fluid as necessary.

6. Test Drive

Sub-steps:
1. Check for any leaks around the transmission and torque converter.
2. Perform a test drive to ensure proper shifting and operation.
