Solution

1. Preparation

Gather the necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick and check the fluid condition; it should be a bright red color and free of debris.
3. If fluid is low or dirty, drain the old fluid using a fluid pump.
4. Replace with manufacturer-recommended transmission fluid (typically Toyota ATF WS).
5. Refill the transmission through the dipstick tube or fill plug, ensuring the proper level is reached.

3. Check and Replace Transmission Filter (if applicable)

Sub-steps:
1. Remove the transmission pan bolts using a socket set and carefully lower the pan.
2. Remove the old filter and replace it with a new one, ensuring it is seated correctly.
3. Clean the transmission pan and magnet before reinstalling.
4. Replace the pan and torque the bolts to the manufacturer’s specifications (usually around 7-10 ft-lbs).

4. Inspect and Replace Engine/Transmission Mounts

Sub-steps:
1. Raise the vehicle safely using jack stands.
2. Visually inspect the engine and transmission mounts for signs of wear or cracking.
3. If damaged, remove the bolts securing the mounts and replace them with new mounts.
4. Torque the new mounts to the manufacturer’s specifications.

5. Check Throttle Position Sensor (TPS)

Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the electrical connector and test the sensor with a multimeter.
3. If the sensor is out of specification (typically 0.5V at closed throttle and around 4.5V at wide open), replace it.
