I usually leave my car in gear while parked, today when I started it up, it violently started jolting forward with clutch pedal engaged. I was able to pull it out with some force. Now it wants to grind any gear that’s not reverse and just hits a wall trying to go into reverse. My question is, could this be something as simple as low fluid or am I looking at more serious issues here. From the research I was able to do it seems likely its a fluid, linkage, or worn cluch problem. I didn’t pay much for the car and most certainly won’t be putting any serious money into a transmission. I can change/add fluid myself, but I’d rather save that money and move on if it’s something more serious.

Any input would be greatly appreciated 🙏
