Solution

1. Preparation

Gather tools: socket set, OBD-II scanner, multimeter, and a transmission fluid dipstick.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery cable to prevent electrical shorts during repairs.

2. Check and Top Off Transmission Fluid

Locate the transmission dipstick or fill plug.
Remove the dipstick and wipe it clean, then reinsert and check the fluid level.
If low, add the appropriate type of transmission fluid (consult the owner’s manual for specifications).
Inspect the fluid for burnt smell or discoloration; if found, a fluid change may be necessary.

3. Inspect Transmission Linkage

Locate the transmission linkage at the transmission and gear shifter.
Check for any loose, damaged, or disconnected components.
If misaligned, adjust or reconnect the linkage as needed.

4. Test Transmission Solenoids

Remove the transmission pan if necessary to access the solenoids.
Use a multimeter to check the resistance of each solenoid according to manufacturer specifications.
Replace any faulty solenoids as needed.

5. Gear Selector Examination

Inspect the gear shifter for any binding or obstruction.
Remove the console cover if necessary to access the shifter mechanism.
Ensure all components are functioning properly; lubricate if necessary.

6. Reassembly and Battery Reconnection

Reattach any components or covers that were removed during inspection.
Reconnect the negative battery cable.
Ensure all tools are removed from the engine bay and under the vehicle.
