Remove the panel covering the gear shifter.
Visually inspect the linkage for any signs of wear or disconnection.
If damaged, replace the gear linkage components.

4. Replace Transmission Fluid (if contaminated)

Tools Required: Fluid pump, container for old fluid.
Place a container under the transmission pan to catch old fluid.
Remove the transmission drain plug and let the fluid drain completely.
Replace the filter if applicable, then reinstall the drain plug.
Fill with fresh transmission fluid through the dipstick tube.
