Elevate the vehicle using a jack and secure it with jack stands.

2. Drain Transmission Fluid

Place a drain pan under the transmission.
Remove the transmission drain plug and allow the fluid to fully drain.
Dispose of the old fluid in accordance with local regulations.

3. Remove the Torque Converter

Remove the bolts securing the torque converter to the flex plate.
Carefully pull the torque converter away from the transmission, ensuring that it does not spill any remaining fluid.
Inspect the converter for any visible damage.

4. Replace Torque Converter Seal

Remove the old seal from the torque converter housing using a seal puller.
Clean the sealing surface thoroughly.
Install the new seal, ensuring it is seated evenly.

5. Reinstall Torque Converter

Align the torque converter with the transmission and push it in until it is fully seated.
Reinstall the bolts to the flex plate, tightening them to the manufacturer’s specified torque settings (typically around 40-50 ft-lbs, but confirm with the service manual).

6. Refill Transmission Fluid

Reinstall the transmission drain plug.
Refill the transmission with the correct type and amount of fluid (consult the owner's manual for specifications).
Start the engine and let it idle, then shift through all gears to circulate the fluid.

7. Final Checks

Reconnect the battery.
Check for leaks around the torque converter and the transmission.
Test drive the vehicle to ensure proper operation.
