5. Reinstall the dipstick or plug securely.

3. Inspect and Replace Clutch (Manual Transmissions Only)

Sub-steps:
1. Remove the transmission from the engine by unbolting the necessary components.
2. Detach the clutch assembly from the flywheel.
3. Inspect the clutch disc, pressure plate, and release bearing for wear.
4. Replace any worn components with OEM parts, ensuring all surfaces are clean.
5. Reassemble the transmission components and torque bolts to manufacturer specifications.

4. Inspect Gear Linkage

Sub-steps:
1. Visually inspect the gear linkage for any signs of damage or misalignment.
2. Adjust or replace damaged linkage components as necessary.
3. Lubricate any moving parts to ensure smooth operation.
