CAN'T CHANGE GEAR ON 512TR!!

Can someone please advise me. Ive made sure the oil is topped up. I can only change gear when the transmission is turned off, but can't when the car is turned on.

Sounds like you might need a new clutch. Can you put it into any gear while the clutch pedal is pressed in all the way? You have a 512TR right?

It is a 512TR. This all happened today within the space of 30 mins:- First I couldn't get it into 1st gear so I had to use 2nd (which was hard to get in), then 3rd was impossible to use. Eventually I couldn't use any gear, only 2nd and REVERSE with a fight. Clutch pedal was pressed in all the way, I could hear creak of the spring under it every time it was pressed.

On some Ferraris you have to wait for the gearbox to warm up before going into second. It could be the same thing now with your car for ALL gears. However, that shouldn't be the case, obviously. Let the car warm up for a bit and try to get it into any gear but don't stray far from the house. Safest thing would be to have it towed. I think you need a new gearbox/clutch.

I'm unsure what sort of clutch actuation-mechanism a TR has.

If it is hydraulic, you could have blown a seal on either the slave or master cylinder. Check around each end of the clutch mechanism (ie at the pedal end & at the clucth end) for signs of fluid leakage. Alternatively you could have run low on fluid & developed an air-lock - check the clutch fluid level & top-up & bleed.

If it is cable / mechanical, something may have gone awry with the linkage - check the pedal connection & at the clutch housing for problems such as missing pins, bolts, etc. What about checking the cable slack & adjusting it (if this is available)?

Finally, is the pedal-feel different to before? Softer, longer-travel, quiter/noisier?

You could have always just gone through the last of the frictional material on the clutch plate but you'd usually get some warning of this - high clutch pedal, excess slippage, etc.
