Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill port.
2. Use a funnel to remove the old fluid; make sure to catch it in a drain pan.
3. Inspect the old fluid for color and odor (should not be burnt).
4. Replace the old transmission fluid with the manufacturer-specified fluid (typically Toyota ATF WS).
5. Recheck the fluid level with the dipstick, adding more fluid if necessary.

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

Sub-steps:
1. Disconnect the electrical connector from the TPS.
2. Remove the mounting screws securing the TPS to the throttle body.
3. Install the new TPS in reverse order, ensuring it is properly aligned.
4. Reconnect the electrical connector and verify the connection is secure.

4. Inspect Engine and Transmission Mounts

Sub-steps:
1. Visually inspect engine and transmission mounts for cracks or signs of wear.
2. If damaged, remove the old mounts by unscrewing the bolts securing them to the frame and engine/transmission.
3. Install new mounts, ensuring they are torqued to the manufacturer's specifications.

5. Reconnect Battery

Reconnect the battery terminals, ensuring a tight connection.
