Visually inspect for any loose, damaged, or disconnected linkage components.
Adjust the linkage if it is out of alignment, ensuring proper connection to the transmission.

4. Replace Transmission Fluid and Filter (if necessary)

Drain the old transmission fluid using a fluid pump or by removing the drain plug.
Replace the transmission filter if it has been determined to be clogged or dirty.
Reinstall the pan (if removed) and tighten bolts to the manufacturer's specified torque.
Refill the transmission with new fluid using the correct type and specifications.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the engine and attempt to shift through the gears to verify if the issue is resolved.
