Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, transmission fluid.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Change Transmission Fluid

Drain Fluid:
- Remove the transmission pan using a socket set.
- Allow old transmission fluid to drain completely into a suitable container.
Replace Filter:
- Remove the old transmission filter and replace it with a new filter.
- Ensure all old gasket material is removed from the pan and the mating surface.
Install Pan:
- Reinstall the transmission pan using a new gasket.
- Torque the pan bolts to the manufacturer’s specified torque (typically around 10-12 ft-lbs).
Refill Transmission Fluid:
- Use a fluid pump to refill the transmission with the appropriate Toyota ATF WS (automatic transmission fluid).
- Check the fluid level using the dipstick, ensuring it is at the correct level.

3. Inspect Torque Converter

Remove Transmission:
- If necessary, support the engine and remove the transmission to access the torque converter.
- Disconnect the torque converter from the flex plate.
Inspect and Replace:
- Inspect the torque converter for damage or excessive wear.
- If damaged, replace the torque converter with a new one.
Reinstall Transmission:
- Reattach the transmission and torque converter, ensuring proper alignment.
- Reconnect all electrical connectors and mounts.
