Clutch Slipping Due to Push Rod Free Play Over-Adjustment

Clutch slipping, potentially worsening as the car heats up. Can occur after clutch hydraulic work (e.g., master cylinder replacement) if the push rod free play is adjusted too tight.

Clutch push rod free play adjusted too tight (no slack), causing the clutch to not fully release. As the car heats up, thermal expansion of hydraulic fluid or components worsens the problem by further engaging the clutch automatically.
