- Remove the dipstick and wipe it clean.
- Reinsert and remove it again to check fluid level; add fluid if low.
- Inspect the fluid for burnt smell or dark color; if necessary, perform a fluid change.

3. Inspect and Adjust Shift Linkage

Sub-steps:
- Locate the shift linkage assembly under the vehicle.
- Check for any visible damage or misalignment.
- If adjustment is needed, loosen the adjustment bolts and align the linkage according to manufacturer specifications before tightening.

4. Clutch Inspection (Manual Transmissions)

Sub-steps:
- Remove the transmission access cover.
