Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety during the process.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, transmission funnel, fluid catch pan.
Remove the transmission fluid drain plug and allow fluid to drain completely into the catch pan.
Replace the drain plug and torque it to manufacturer specifications (consult the service manual for the specification).
Refill the transmission with the recommended type of transmission fluid using a funnel until it reaches the proper level.

3. Replace Transmission Filter

Tools Required: Socket set, screwdrivers, gasket scraper.
Locate the transmission filter and remove any retaining screws or clips.
Carefully remove the old filter and discard it.
Clean the mounting surface to remove any old gasket material.
Install the new transmission filter and secure it with screws or clips.

4. Inspect and Adjust Throttle Position Sensor

Tools Required: Multimeter.
Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and check the voltage output using the multimeter while manually moving the throttle.
If the readings are out of specification, adjust or replace the sensor as needed.

5. Test Drive and Recheck Fluid Level

After completing repairs, take the vehicle for a test drive to ensure proper shifting behavior.
After the test drive, park the vehicle and recheck the transmission fluid level, adding more fluid if necessary.
