Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent any electrical issues during the repair.

2. Check and Replace Transmission Fluid

Tools Required: Transmission funnel, socket set, torque wrench.
Locate the transmission drain plug and remove it to drain the old fluid into a pan.
Replace the drain plug and torque it to the manufacturer’s specifications (usually around 30-40 ft-lbs).
Remove the transmission fluid fill plug and use a funnel to add new transmission fluid (Toyota WS fluid recommended) until it reaches the correct level on the dipstick.
Reinstall the fill plug and torque to specifications.

3. Inspect and Replace Transmission Filter (if applicable)

Tools Required: Socket set, transmission filter kit.
Remove the transmission pan by unscrewing the bolts; this may require a gasket scraper to separate the pan from the transmission.
Inspect the old filter and replace it with a new one.
Clean the transmission pan and ensure the magnet is free of debris.
Install a new gasket and reattach the pan, torquing bolts to manufacturer specifications.

4. Electrical Check

Tools Required: Multimeter.
Inspect the transmission range sensor for proper voltage and continuity.
Check the wiring and connectors for any signs of damage or corrosion.
Replace any faulty components as necessary.
