Solution

1. Preparation

Tools Required:
- OBD-II scanner
- Torque wrench
- Socket set
- Fluid pump
Ensure the vehicle is on a level surface and the engine is off before starting work.
Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Using a fluid pump, drain the old transmission fluid into a suitable container.
3. Inspect the old fluid for metal shavings or burnt odor indicating severe wear.
4. Replace the transmission filter if applicable (follow manufacturer guidelines).
5. Refill with the manufacturer-recommended transmission fluid (typically Toyota WS fluid).
6. Start the engine and cycle through the gears to allow fluid to circulate, then recheck the fluid level and add as necessary.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Raise the vehicle securely on jack stands.
2. Inspect the transmission mounts for cracks or excessive wear.
3. If damaged, remove the bolts securing the mounts using a socket set.
4. Replace with new mounts, ensuring they are torqued to manufacturer specifications.
5. Lower the vehicle back to the ground.

4. Reprogram Transmission Control Module (if necessary)

Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Follow the scanner's instructions to reprogram or reset the TCM based on any fault codes retrieved.
3. Clear any codes and test drive to check for improvements in transmission performance.
