Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, screwdriver, transmission fluid pump.
Ensure the vehicle is on a level surface and securely raised with jack stands.
Disconnect the battery to prevent any electrical issues during repairs.

2. Change Transmission Fluid and Filter

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts with a socket set.
2. Drain the old transmission fluid into a suitable container.
3. Replace the transmission filter: unclip and remove the old filter, then install the new filter.
4. Clean the transmission pan and replace the pan gasket if necessary.
5. Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications (usually around 10-12 ft-lbs).

3. Install Torque Converter Treatment

Sub-steps:
1. Use a torque converter shudder treatment additive specifically designed for automatic transmissions.
2. Pour the treatment into the transmission fluid dipstick tube after replacing the fluid.
3. Run the engine for a few minutes to allow the treatment to circulate.

4. Test Drive

Sub-steps:
1. Reconnect the battery and start the vehicle, checking for any leaks.
2. Take the vehicle for a test drive to monitor for shuddering.
3. If shuddering persists, further inspection of the torque converter and transmission may be necessary.
