Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a level surface.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Transmission fluid pump
- Drain pan
Safety Warnings:
- Disconnect the battery before working on electrical systems.
- Allow the engine to cool before working on transmission components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it. Wipe it clean with a lint-free cloth.
2. Reinsert the dipstick and remove it again to check the fluid level.
3. If the fluid is low, use a transmission fluid pump to add the recommended type (Toyota ATF WS).
4. If the fluid is dirty or has a burnt smell, drain the old fluid into a drain pan.
5. Remove the transmission pan (if necessary) and replace the filter.
6. Reinstall the pan and torque the bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs).
7. Refill with new transmission fluid to the appropriate level.

3. Inspect and Replace Transmission Mount

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Locate the transmission mount and inspect for cracks or wear.
3. If damaged, remove the bolts securing the mount to the transmission and the chassis.
4. Install the new mount and torque the bolts to specifications.
5. Lower the vehicle and test for improvements.

4. Test the Transmission Range Sensor

Sub-steps:
1. Locate the transmission range sensor on the side of the transmission.
2. Disconnect the electrical connector.
3. Use a multimeter to test continuity and voltage according to specifications.
4. Replace the sensor if it is faulty, following manufacturer guidelines for installation.
