Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Check and Replace Transmission Fluid

Tools Required: Transmission funnel, new transmission fluid, drain pan.
Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Use a funnel to add new transmission fluid if the level is low.
3. If fluid is burnt or contaminated, drain the transmission fluid using a drain pan.
4. Replace with the manufacturer-recommended transmission fluid (typically ATF WS for Toyota).

3. Inspect and Replace Transmission Mounts

Tools Required: Socket set, floor jack, jack stands.
Sub-steps:
1. Lift the vehicle using a floor jack and secure it with jack stands.
2. Locate the transmission mounts; visually inspect for cracks or excessive wear.
3. Remove the bolts securing the damaged mount using a socket set.
4. Install the new mount, ensuring all bolts are torqued to manufacturer specifications.

4. Test and Replace Throttle Position Sensor (if faulty)

Tools Required: Multimeter, socket set.
Sub-steps:
1. Disconnect the throttle position sensor connector.
2. Use a multimeter to test the sensor's resistance; compare with specifications.
3. If defective, remove the sensor using a socket set and install the new sensor.
4. Reconnect the sensor and clear any codes from the OBD-II scanner.
