Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely raised using jack stands.
Disconnect the vehicle's battery to prevent electrical issues.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level.
2. If fluid is low, add the manufacturer-recommended transmission fluid.
3. If old or burnt fluid is present, drain the old fluid using a drain pan.
4. Replace with new fluid, ensuring the correct type and quantity is used (typically Toyota ATF WS).
Tools Required: Transmission fluid pump, drain pan, funnel.

3. Inspect and Replace Transmission Mounts

Sub-steps:
1. Locate the transmission mounts and inspect for cracks or excessive wear.
2. If damaged, remove the bolts securing the old mounts using a socket set.
3. Install new transmission mounts, ensuring they are properly aligned.
4. Torque the bolts to manufacturer specifications (typically around 40-50 ft-lbs).
Tools Required: Socket set, torque wrench.

4. Inspect Engine Mounts

Sub-steps:
1. Check engine mounts for signs of damage or excessive wear.
2. Remove any fasteners securing the engine mounts if replacement is necessary.
3. Install new engine mounts and tighten to specifications.
Tools Required: Socket set.

5. Test Transmission Solenoids

Sub-steps:
1. Disconnect the electrical connectors from the solenoids.
2. Use a multimeter to measure resistance; compare readings to specifications (consult the repair manual).
3. Replace any faulty solenoids.
Tools Required: Multimeter.
