Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported (use jack stands if necessary).
Disconnect the battery to prevent electrical issues.

2. Change Transmission Fluid

Drain Old Fluid
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan and allow old fluid to drain into a catch basin.
- Clean the pan and magnet to remove any metal shavings.
Replace Filter
- Remove the old transmission filter and discard it.
- Install the new filter, ensuring it is seated correctly.
Install New Fluid
- Reinstall the transmission pan with a new gasket, tightening bolts to the manufacturer-specified torque (typically around 8-10 ft-lbs).
- Refill the transmission with the recommended type of fluid (usually Toyota ATF WS) through the dipstick tube, following the manufacturer's specified capacity.

3. Inspect and Replace Throttle Position Sensor (if necessary)

Locate the TPS
- Find the throttle body and locate the TPS on it.
Remove the TPS
- Disconnect the electrical connector.
- Unscrew the TPS and remove it from the throttle body.
Install New TPS
- Position the new TPS and secure it with screws.
- Reconnect the electrical connector.
