Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick, remove it, and wipe it clean.
2. Insert the dipstick back into the tube, then remove it again to check the fluid level.
3. If the fluid is low, add the correct type of transmission fluid (Toyota ATF WS).
4. If the fluid is dark or has a burnt smell, proceed to drain and replace it.
Tools Required: Transmission fluid pump, funnel, 10mm socket.
Safety Warnings: Always allow the engine to cool before handling the transmission fluid.

3. Replace the Transmission Filter

Sub-steps:
1. Place a drain pan under the transmission pan to catch fluid.
2. Remove the bolts securing the transmission pan using a socket.
3. Carefully lower the pan and remove the old filter.
4. Install the new filter, ensuring it is seated properly.
5. Clean the transmission pan and replace the gasket before reinstalling.
Tools Required: Socket set, torque wrench.
Safety Warnings: Use gloves to protect hands from sharp edges of the pan.

4. Inspect and Test Transmission Solenoids

Sub-steps:
1. Remove the electrical connectors from the transmission solenoids.
2. Use a multimeter to test the resistance of each solenoid according to specifications.
3. Replace any faulty solenoids with new components.
Tools Required: Multimeter, socket set.
Safety Warnings: Ensure the battery is disconnected before working on electrical components.
