Solution

1. Preparation

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

2. Change Transmission Fluid

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts with a socket set and carefully lower the pan to drain the old fluid.
4. Clean the pan and replace the filter.
5. Reinstall the pan with a new gasket and torque the bolts to the manufacturer's specifications (usually around 10-12 ft-lbs).
6. Refill the transmission with new fluid using the manufacturer-recommended type (typically Toyota ATF WS).

3. Inspect and Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage connected to the gear shifter.
2. Inspect for any damage or misalignment.
3. Adjust the linkage as necessary to ensure proper alignment and function.
4. Test the shifter for smooth operation after adjustment.

4. Replace Throttle Position Sensor (if faulty)

Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector and remove the mounting screws.
3. Install the new throttle position sensor and reconnect the electrical connector.
4. Clear any codes from the OBD-II system after installation.
