Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
Remove the transmission fill plug and check fluid level.
If low, add the recommended Toyota ATF WS fluid until it reaches the correct level.
If fluid condition is poor, drain the fluid by removing the drain plug and replace it with fresh ATF WS fluid.
Torque the drain plug to the factory specifications (typically around 25 ft-lbs).

3. Inspect and Replace Transmission Filter (if applicable)

Remove the transmission pan by unscrewing all bolts and allowing fluid to drain.
Replace the transmission filter located inside the pan.
Clean the pan and install a new gasket.
Reinstall the transmission pan and torque bolts to the recommended specifications (usually 7-9 ft-lbs).

4. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and allow it to reach operating temperature.
Test drive the vehicle to ensure that the jerking issue has been resolved.
