Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Fluid Change

Raise the vehicle using a jack and secure it with jack stands.
Use a socket set to remove the transmission pan bolts.
Carefully lower the transmission pan and drain the old fluid into a suitable container.
Replace the transmission filter if applicable.
Reinstall the transmission pan with a new gasket. Torque the bolts to the manufacturer's specification (typically around 8-10 ft-lbs).
Refill the transmission with new fluid (Toyota WS fluid recommended) through the dipstick tube.

3. Torque Converter Solenoid Inspection/Replacement

Locate the torque converter lock-up solenoid, typically found on the valve body of the transmission.
Disconnect the electrical connector attached to the solenoid.
Remove the mounting bolts securing the solenoid using a socket set.
Replace the solenoid with a new unit. Ensure it matches OEM specifications.
Reconnect the electrical connector and ensure it snaps into place.

4. Test Drive

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Take the vehicle for a test drive to ensure that the shudder has been resolved and that the transmission operates smoothly.
