Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check the fluid level.
2. If low, add the appropriate type of transmission fluid (Toyota ATF WS).
3. If the fluid is dark or has a burnt smell, a fluid change is necessary.
4. To change the fluid, remove the transmission pan (if applicable) and drain the old fluid.
5. Replace the transmission filter (if applicable) and reassemble.
6. Refill with new transmission fluid to the proper level using a funnel.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Visually inspect the transmission mounts for signs of wear or damage.
2. If damaged, support the transmission with a jack and remove the bolts securing the mount.
3. Replace the old mount with a new one and torque the bolts to manufacturer specifications (consult service manual for torque values).

4. Diagnose and Replace Faulty Solenoids

Sub-steps:
1. Remove the transmission pan again to access the solenoids.
2. Disconnect the electrical connectors from the solenoids.
3. Test each solenoid with a multimeter and replace any that are outside the specified resistance range.
4. Reassemble the transmission pan and refill with fluid.
