Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Transmission Fluid

Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
Remove the transmission drain plug and drain the old fluid into a suitable container.
Replace the transmission filter (if applicable) by removing the transmission pan (follow separate instructions for transmission pan removal).
Reinstall the drain plug and torque to the manufacturer specifications.
Fill with new transmission fluid using a transmission fluid pump and funnel, ensuring to use the recommended type (typically Toyota ATF WS).

3. Inspect and Replace Transmission Mount

Tools Required: Jack, jack stands, socket set.
Safely lift the vehicle and support it with jack stands.
Locate the transmission mount; visually inspect for cracks or excessive wear.
Remove the old mount by unscrewing the bolts and replace it with a new mount.
Torque the new mount to the manufacturer specifications.

4. Test and Replace Transmission Solenoids

Tools Required: Multimeter, socket set.
Locate the transmission solenoids; disconnect the electrical connectors.
Use a multimeter to test the resistance of each solenoid according to specifications.
If any solenoid is out of range, replace it with a new one.
Reconnect the electrical connectors after replacement.
