Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and secured with wheel chocks.
Disconnect the battery before working on electrical components.

2. Transmission Fluid Change

Sub-steps:
1. Locate the transmission fluid pan and remove the drain plug (if equipped) or the pan itself.
2. Allow the old transmission fluid to drain completely into a suitable container.
3. Inspect the pan for metal shavings or debris which may indicate internal wear.
4. Replace the transmission filter (if applicable) by unscrewing it and installing the new filter.
5. Reinstall the drain plug or transmission pan with a new gasket, tightening to manufacturer specifications (generally around 10-12 ft-lbs).
6. Refill the transmission with new fluid as per manufacturer specifications (typically Toyota Type T-IV or WS fluid), using a funnel.

3. Inspect and Adjust Shift Linkage

Sub-steps:
1. Visually inspect the shift linkage for corrosion, wear, or loose connections.
2. If adjustments are needed, locate the adjustment points on the linkage.
3. Adjust the linkage according to the service manual specifications to ensure proper alignment and function.

4. Replace Transmission Range Sensor (if faulty)

Sub-steps:
1. Disconnect the electrical connector from the range sensor.
2. Remove the sensor from its mounting position using the appropriate socket size.
3. Install the new sensor and connect the electrical harness.
4. Clear any diagnostic codes related to the transmission range sensor from the OBD-II scanner.
