Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel.
Ensure the vehicle is on a level surface and set the parking brake.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check and Top Off Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe the dipstick clean, reinsert, and check the fluid level.
If low, add the appropriate transmission fluid type as specified in the owner's manual using a funnel.

3. Inspect Clutch (Manual Transmission Only)

Remove the inspection cover if equipped.
Check the clutch master cylinder for fluid level and leaks.
If necessary, bleed the clutch system to remove air bubbles.

4. Examine Transmission Linkage

Inspect the linkage for wear or misalignment.
If damaged, replace the linkage components following the manufacturer’s specifications.

5. Check for Diagnostic Codes

Reconnect the negative battery terminal.
Use an OBD-II scanner to check for any transmission-related trouble codes.
Address any specific codes by following the manufacturer's repair guidelines.
