Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, fluid catch pan.
Remove the transmission pan bolts using a socket set, and carefully lower the pan to drain old fluid into the catch pan.
Inspect the pan for metal shavings or debris; clean the pan and replace the filter if necessary.
Refill with the manufacturer-recommended transmission fluid (Toyota WS fluid) using a fluid pump.

3. Inspect and Replace Shift Solenoids

Tools Required: Socket set, torque wrench.
Locate the transmission solenoids (usually on the valve body).
Remove the electrical connectors and bolts securing the solenoids.
Replace any faulty solenoids with new ones and reassemble, ensuring proper torque specifications are followed.

4. Inspect and Adjust Transmission Range Sensor

Tools Required: Screwdriver, multimeter.
Locate the transmission range sensor, usually on the side of the transmission.
Check the alignment of the sensor; adjust if misaligned.
Test the sensor with a multimeter to ensure it operates within specified parameters.
