Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and wipe it clean.
2. Using a funnel, add fresh transmission fluid if low. Use Toyota WS fluid specified for this model.
3. Start the engine and shift through all gears while monitoring fluid levels with the dipstick.
4. If fluid is dark or burnt, proceed to drain and replace.
Tools Required: Transmission fluid pump, funnel, socket set.
Safety Warnings: Ensure the engine is cool before working on the transmission.

3. Inspect and Replace Transmission Mounts (if necessary)

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Locate and visually inspect the transmission mounts for cracks or excessive wear.
3. If damaged, unbolt the old mounts using a socket set and replace with new mounts.
4. Torque the new mounts to the manufacturer’s specifications.
Tools Required: Socket set, torque wrench.
Safety Warnings: Always use jack stands; do not rely solely on a hydraulic jack.

4. Test Transmission Solenoids

Sub-steps:
1. Disconnect the electrical connector to the transmission solenoids.
2. Use a multimeter to check resistance values; compare with manufacturer specifications.
3. If out of spec, replace the faulty solenoid(s).
4. Reconnect electrical connectors after replacement.
Tools Required: Multimeter, socket set for solenoid removal.
Safety Warnings: Ensure the battery is disconnected during electrical work.
