Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Transmission fluid dipstick
- Fluid pump (for fluid change)
Safety Warnings:
- Disconnect the battery before working on electrical systems.
- Allow engine to cool before opening the transmission.

2. Check and Change Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick and remove it to check fluid level.
2. If low, use a fluid pump to add the manufacturer-recommended transmission fluid (Toyota ATF WS).
3. If fluid is dirty or burnt, proceed to drain the transmission fluid.
4. Remove the transmission drain plug (if applicable) and allow fluid to completely drain into a catch pan.
5. Replace the drain plug and torque it to the manufacturer’s specifications (usually around 30 ft-lbs).
6. Refill with new transmission fluid through the dipstick tube, ensuring the correct amount is added (check the owner’s manual for specifics).

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect the transmission mounts for cracks or excessive wear.
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.

4. Reprogram Transmission Control Module (if required)

Sub-steps:
1. Connect the OBD-II scanner to the vehicle's diagnostic port.
2. Access the transmission control module settings and check for available software updates.
3. Follow the manufacturer's instructions to update or reprogram the module if necessary.
