Disconnect the battery to ensure safety while working on electrical components.

2. Fluid Change

Tools Required: Socket set, funnel, transmission fluid pump, drain pan.
Sub-steps:
1. Remove the drain plug from the transmission pan and allow the old fluid to drain completely into the pan.
2. Replace the drain plug with a new gasket and torque to manufacturer's specifications.
3. Remove the transmission fluid dipstick, and using a funnel, refill the transmission with fresh fluid according to the manufacturer's specifications.
4. Start the engine and allow it to run for a few minutes, then cycle through the gear positions to circulate the fluid.

3. Torque Converter Replacement (if necessary)

Tools Required: Socket set, torque wrench, transmission jack.
Sub-steps:
1. Remove the transmission pan and filter to access the torque converter.
2. Disconnect the torque converter from the transmission.
3. Remove the old torque converter and install the new one, ensuring it is seated properly.
4. Reinstall the transmission pan and filter, using new gaskets.
5. Refill the transmission fluid.

4. Final Checks

Tools Required: OBD-II scanner.
Sub-steps:
1. Reconnect the battery.
2. Clear any error codes using the OBD-II scanner.
3. Test drive the vehicle to ensure smooth operation and confirm that the shuddering issue is resolved.
