Clutch stuck to floor?

[collateral]

Alright my turn for a tech question. I recently bought a 2012 gt with the mt82 and the car i know had a new engine put in no knowledge of anything else. But ever since I bought the car its had a notch 1st-2nd and will occasionally lockout 3rd and sometimes burn the clutch when shifting into 3rd in high rpm. Just been really careful with it cause im not to knowledgeable on these transmissions. Well the other day I was just cruising and when I shifted the clutch stuck to the floor but the clutch engaged then the clutch popped back up on its own after a few seconds. So my first thought was to just bleed the clutch to make sure it was bleed properly if any previous work was done, and I felt that could be the cause for all the problems im having. Well I did the thing where you hook a vacuum pump up and its not building vacuum, it just keeps sucking fluid through and I keep having to top it off and empty it. The clutch has pressure, but im not sure what a stock clutch should feel like. But me personally it feels kinda spongy. So my question am I dealing with a bad slave? Master cylinder?

New engine you would think they put in new clutch. If not, you need to. That trans wont tolerate abuse, and a bad clutch=abuse.
That trans is coming out.

same opinion here.. you need to pull out the transmission, to check the clutch components .
The clutch job is way cheaper than a tranny ../ tranny rebuild
