5. Follow the same process for the slave cylinder located near the transmission.

4. Inspect Clutch Pedal Assembly

Sub-steps:
1. Remove the lower dash cover to access the clutch pedal assembly.
2. Check for any binding or resistance in the pedal movement.
3. Lubricate pivot points with white lithium grease if necessary.
4. Tighten any loose bolts securing the pedal assembly.

5. Adjust Clutch Release Mechanism

Sub-steps:
