Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Tools Required: OBD-II scanner, socket set, multimeter, fluid pump, torque wrench, funnel.
Safety Warnings: Disconnect the battery before working on electrical systems.

2. Transmission Fluid Change

Step 1: Raise the vehicle securely on jack stands.
Step 2: Locate the transmission drain plug and drain the old transmission fluid into a pan.
Step 3: Remove the transmission pan (if applicable) to access the filter.
- Sub-step: Use a socket set to remove the bolts securing the pan, and carefully lower it.
Step 4: Replace the transmission filter with a new one.
Step 5: Clean the pan and magnet (if equipped) of any debris before reinstallation.
Step 6: Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications (typically around 10-12 ft-lb).
Step 7: Refill the transmission with new fluid through the dipstick tube using a funnel, ensuring to use the recommended fluid type (Toyota ATF WS).

3. Solenoid Replacement (if necessary)

Step 1: If solenoid tests indicate failure, remove the transmission pan again.
Step 2: Disconnect the electrical connectors from the solenoids.
Step 3: Remove the faulty solenoids by unbolting them.
Step 4: Install new solenoids and reconnect the electrical connectors.
Step 5: Reinstall the transmission pan and refill the transmission fluid as previously described.

4. Final Checks

Step 1: Reconnect the battery.
Step 2: Start the vehicle and let it idle, checking for leaks.
Step 3: Test drive the vehicle to ensure the jerking issue is resolved.
