Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fluid catch pan.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Insert the dipstick back and remove it again to check the fluid level. If low, add the recommended ATF (Automatic Transmission Fluid).
Inspect the fluid for color and smell; if it’s dark or has a burnt odor, consider a fluid change.

3. Inspect Transmission Linkage

Locate the transmission linkage under the vehicle.
Check for any loose or damaged components; tighten or replace as necessary.
Ensure the linkage moves freely without obstruction.

4. Test Transmission Solenoids

Access the transmission solenoids, typically located on the valve body.
Disconnect the electrical connectors and measure resistance with a multimeter.
Compare readings to manufacturer specifications; replace any faulty solenoids.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the vehicle and attempt to shift through the gears.
Monitor for smooth operation and listen for unusual noises.
