Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Ensure the engine is off and the parking brake is engaged.
Tools Required: OBD-II scanner, socket set, fluid catch pan, funnel, and rags.

2. Check Transmission Fluid

Locate the transmission dipstick (if applicable).
Remove the dipstick, wipe it clean, and reinsert it fully.
Remove it again and check the fluid level; add the appropriate transmission fluid if low.
Inspect the fluid's color and smell; if burnt or dark, consider a fluid change.

3. Inspect Shifter Linkage

Remove the center console cover to access the shifter linkage.
Check for any loose or disconnected linkages; reattach or tighten as necessary.
Ensure the shifter moves smoothly through the gears; lubricate if necessary.

4. Examine Electrical Connections

Disconnect the battery before working on electrical components.
Locate the transmission control module and check all electrical connectors for corrosion or damage.
Use a multimeter to test voltage at the module; repair or replace any faulty wiring.

5. Test Transmission Operation

Reconnect the battery and start the engine.
With the vehicle in park, check if the engine revs freely.
Attempt to shift into drive or reverse; listen for any unusual sounds that might indicate internal transmission issues.
