Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, transmission fluid, funnel, fluid catch pan, torque wrench.
Safety Warnings: Disconnect the battery before working on electrical systems. Allow the engine to cool before working on the transmission.

2. Fluid Change and Filter Replacement

Drain the Transmission Fluid
- Position the fluid catch pan under the transmission pan.
- Remove the transmission pan bolts using a socket set.
- Carefully lower the pan and allow the fluid to drain completely.
Replace the Transmission Filter
- Remove the old filter from the transmission.
- Clean the filter mounting surface with a lint-free cloth.
- Install the new filter securely, ensuring it is seated properly.
Reattach the Transmission Pan
- Clean the transmission pan and apply a new gasket or sealant as per manufacturer's specifications.
- Reinstall the pan and torque the bolts to the manufacturer's specifications (check owner's manual for torque values).
Refill Transmission Fluid
- Using a funnel, fill the transmission with new fluid through the dipstick tube, ensuring to use the recommended type (usually Toyota ATF WS).
- Check the fluid level with the engine running and add fluid as necessary to reach the correct level.

3. Sensor and Mount Inspection

Throttle Position Sensor
- Disconnect the electrical connector from the throttle position sensor.
- Use a multimeter to test the sensor according to the specifications in the service manual.
- Replace the sensor if it is faulty.
Transmission Mounts
- Visually inspect the transmission mounts for cracks, tears, or excessive wear.
- If damaged, remove the bolts securing the mounts and replace them with new ones.
