Clutch, maybe slave cylinder

[venturawildes]

I was driving home and it felt like something gave or broke in the clutch system. The pedal kind of suddenly went to the floor and the car became hard to shift. Clutch still has pressure but pedal feels very light. Car creeps when in 1st and clutch depressed. Any ideas?

Ok, first thing, very easy to check, is there any brake fluid in the reservoir (frunk)?

Otherwise....

I would guess 1.) you have air in the brake/clutch system, 2.) your slave cylinder failed, or 3.) you have failed clutch parts (transmission has to be removed and parts replaced).

It felt like something broke, car has 83K on it, perhaps time for a new clutch. Local indy will do it for 1500, seems very reasonable, throw in a 1k for the IMS upgrade.

Probably the diaphragm spring of the pressure plate broken, this does happens regulary especially when the clutch pedal pressure becomes too high (hardens)

Say about 2 hours trans in, 2 hours trans out, 1 hour replace clutch parts, new clutch kit retail $700-800 (450 ebay).

5 hours @ say $125 hr yes 1500 is in ballpark.

If they've done IMS before sure have that done too, especially if yours is a single row car.

Does the flywheel have to be replaced also? Adds a lot of cost.

83K on a flywheel is a lot of miles. If the flywheel surface is really worn out, your new clutch may not last as long. Resurfacing dual mass flywheels is not something most shops will do. That being said, if the flywheel springs check out and the surface is not terrible then I can't see why you couldn't keep using it (aside from the new clutch disc not lasting as long).
