Solution

1. Preparation

Gather required tools and parts.
Disconnect the negative terminal of the battery to ensure safety before beginning work.

2. Transmission Fluid Inspection

Remove the transmission dipstick (if applicable) and wipe it clean.
Insert it back and remove it again to check the fluid level.
If low, add the specified transmission fluid (refer to the owner's manual for the correct type).
If the fluid is burnt or discolored, proceed to replace it and the transmission filter.

3. Throttle Position Sensor Replacement

Locate the throttle position sensor on the throttle body.
Disconnect the electrical connector and remove any mounting screws.
Install the new throttle position sensor, ensuring it is aligned properly.
Reconnect the electrical connector.

4. Vacuum Leak Repair

Visually inspect vacuum hoses for cracks or disconnections.
Use a smoke machine or spray soapy water around suspected areas while the engine is running to identify leaks.
Replace any damaged hoses.

5. Transmission Linkage Adjustment

Inspect the transmission linkage for any wear or misalignment.
Adjust the linkage as necessary, ensuring it shifts correctly into all gears.
