On 1/17 - My clutch peddle was to the floor. This has never happened before. I pumped the clutch, the car started but the gears would not shift. The gears only shift when the car is off. I'm wondering if the car has a cable that snapped or if there may be a possible leak.
Does my car have a clutch cable? on 1999 Nissan Maxima
It sounds as if your clutch master cylinder is leaking or out of fluid. Go to google and enter clutch master cylinder for your car and it will show you where it is located so you can check fluid level as long as it is not located inside trans casing.
