2. Remove Transmission Fluid

Tools Required: Drain pan, socket set.
Remove the transmission drain plug and allow the fluid to drain completely.
Replace the drain plug and tighten to manufacturer specifications.

3. Inspect and Replace Torque Converter

Tools Required: Socket set, torque wrench, transmission jack.
Remove the transmission from the vehicle by following these sub-steps:
1. Disconnect the battery and remove any electrical connectors or wiring harnesses.
2. Remove the drive axles and any components obstructing the transmission.
3. Unbolt the transmission from the engine and support the transmission with a jack.
4. Carefully lower the transmission from the vehicle.
Remove the old torque converter from the transmission by unbolting it.
Install the new torque converter by aligning it properly and securing it with bolts.

4. Reinstall Transmission

Reinstall the transmission by reversing the removal steps.
Ensure all bolts are torqued to manufacturer specifications.
Fill the transmission with the correct type of fluid as specified in the owner's manual.

5. Test Drive

Reconnect the battery and start the vehicle.
Perform a test drive to ensure proper operation of the transmission and torque converter.
