Solution

1. Preparation

Gather tools and parts necessary for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery before beginning work.

Tools Required:

OBD-II scanner
Socket set
Torque wrench
Transmission fluid pump
Multimeter
Screwdrivers

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission fluid dipstick and remove it.
2. Check the fluid level; if low, add the recommended transmission fluid (Toyota ATF WS).
3. If the fluid appears dark or has a burnt smell, proceed to drain and replace it.
4. Remove the transmission drain plug and allow fluid to completely drain into a pan.
5. Replace the drain plug and torque to the manufacturer’s specifications (typically around 30 ft-lbs).
6. Refill the transmission with new fluid using the fluid pump through the dipstick tube until it reaches the proper level.

3. Inspect and Replace Transmission Mounts (if necessary)

Sub-steps:
1. Raise the vehicle using jack stands for safety.
2. Visually inspect the transmission mounts for cracks or excessive wear.
3. If mounts are damaged, remove the bolts securing them to the transmission and body.
4. Install new mounts and torque bolts to specifications.

4. Test and Replace Throttle Position Sensor (if necessary)

Sub-steps:
1. Disconnect the electrical connector from the TPS.
2. Use a multimeter to test the TPS resistance; compare readings to manufacturer specifications.
3. If the TPS is faulty, remove it from the throttle body.
4. Install a new TPS and reconnect the electrical connector.
