Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Check and Change Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure with jack stands.
2. Remove the transmission fluid drain plug and drain the old fluid into a pan.
3. Remove the transmission pan using a socket set, and replace the transmission filter if needed.
4. Clean the pan and magnet to remove debris.
5. Reinstall the transmission pan with a new gasket and torque to manufacturer specifications (typically 10-12 ft-lbs).
6. Refill with fresh transmission fluid (check the manual for the correct type; typically, Toyota WS fluid) through the dipstick tube.

3. Inspect and Adjust Shift Linkage

Sub-steps:
1. Visually inspect the shift linkage for any broken or disconnected components.
2. If misaligned, adjust the linkage according to the service manual specifications.
3. Test the movement of the shifter and ensure it engages in all positions.

4. Replace Throttle Position Sensor (if faulty)

Sub-steps:
1. Disconnect the battery to prevent electrical shorts.
2. Locate the throttle position sensor on the throttle body.
3. Unplug the electrical connector and remove the mounting screws.
4. Install the new sensor, securing it with screws and reconnecting the electrical connector.
5. Reconnect the battery.
