Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Tools Required: Transmission funnel, fluid pump, torque wrench.
Remove the transmission fill plug and check the fluid level.
If fluid is low, add the recommended type of transmission fluid (Toyota WS fluid).
If the fluid is burnt or contaminated, drain the transmission fluid by removing the transmission pan.
Replace the old fluid with new fluid and reassemble the transmission pan using a new gasket.

3. Inspect and Adjust Transmission Linkage

Tools Required: Socket set, adjustable wrench.
Visually inspect the transmission linkage for any signs of wear or damage.
If misaligned, adjust the linkage according to the manufacturer's specifications.
Tighten all bolts securely to prevent future misalignment.

4. Replace Transmission Range Sensor

Tools Required: Socket set, screwdrivers.
Locate the transmission range sensor on the transmission case.
Disconnect the wiring harness and remove the mounting screws.
Install the new range sensor and reconnect the wiring harness.
Ensure that the sensor is properly calibrated following the manufacturer's instructions.
