Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues while working on the transmission.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, drain pan, funnel.
Remove the transmission drain plug and allow the old fluid to drain completely into the drain pan.
Inspect the drain plug for metal shavings or debris; replace if necessary.
Replace the drain plug and torque it to the manufacturer's specifications (usually around 30 lb-ft).
Use a transmission fluid pump to refill the transmission with the appropriate type of fluid (typically Toyota WS fluid).

3. Inspect and Replace Transmission Filter

Tools Required: Socket set, filter removal tool, gasket scraper.
Remove the transmission pan by unscrewing the bolts; be cautious of fluid spillage.
Remove the old filter and replace it with a new filter from a reputable manufacturer.
Clean the pan and magnet (if equipped) to remove any debris.
Install a new gasket and reattach the transmission pan, torquing the bolts to the specified value (typically 8 lb-ft).

4. Test and Replace Solenoids (if necessary)

Tools Required: Multimeter, socket set.
If solenoids are defective from the previous diagnostic step, remove the transmission valve body to access the solenoids.
Disconnect the electrical connectors and remove the solenoids.
Install new solenoids and reassemble the valve body, ensuring proper torque specifications are followed.
