Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if applicable) and remove it.
2. Check the fluid level and condition; add new fluid if low.
3. If the fluid is dark or burnt, drain the old fluid using a wrench on the transmission pan bolts.
4. Replace the filter if equipped (remove the pan and old filter, install the new filter).
5. Reinstall the pan and torque the bolts to manufacturer specifications (typically around 10-12 ft-lbs).
6. Fill the transmission with new fluid via the dipstick tube, ensuring you use the correct type (typically Toyota ATF WS).

3. Inspect and Replace Transmission Range Sensor (if faulty)

Sub-steps:
1. Locate the transmission range sensor on the side of the transmission.
2. Disconnect the electrical connector and remove the mounting bolts.
3. Install the new range sensor, ensuring it is aligned correctly.
4. Reconnect the electrical connector and test for proper operation before securing.

4. Check and Adjust Shift Linkage

Sub-steps:
1. Inspect the shift linkage for any signs of wear or disconnection.
2. Adjust the linkage as needed to ensure it engages the transmission correctly.
3. Test the shifting action to confirm proper engagement.
