Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check fluid level.
2. If low, add the correct type of ATF (Toyota WS fluid recommended).
3. If the fluid is discolored or burnt, drain the old fluid using a fluid pump.
4. Replace with new ATF, ensuring the transmission is filled to the correct level.

3. Inspect and Replace Transmission Mounts (if damaged)

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Locate the transmission mounts and visually inspect for cracks or excessive wear.
3. If damaged, unbolt the old mounts using a socket set.
4. Install new mounts, ensuring all bolts are torqued to manufacturer specifications.

4. Throttle Position Sensor (TPS) Inspection

Sub-steps:
1. Locate the TPS on the throttle body.
2. Disconnect the electrical connector.
3. Using a multimeter, check the voltage output.
4. If the TPS is faulty, replace it with a new one and reconnect the connector.

5. Transmission Control Module (TCM) Update

Sub-steps:
1. Connect a diagnostic scanner to the OBD-II port.
2. Check for software updates for the TCM.
3. If available, follow the manufacturer's instructions to update the TCM software.
