Stuck in 1st gear!!!!!

[aaronolwell]

HELP!!! My 300TD is stuck in 1st gear!(4-sp manual) The gear shift won't move sideways or front to back at all, and while the position it's in looks more like neutral it is definitely in 1st gear! I can start the car (with the clutch in) and clutch out just like normal, so i can drive her but not shift. Information of uncertain value: I topped the brake/clutch fluid up yesterday upon noticing it was getting lower for the first time i'd noticed. There also seems to be a slight bit of leakage around the line that comes away from the clutch pedal. Any ideas, anyone?
