Problem with transmission downshifting while slowing down. When cold, the transmission gives a big jolt when downshifting. As the car heats up the problem disappears. Did the 30k service which included tranny service but problem remains.

8000 mi clutch falls to floor on a soft foot. clutch pressure not spec. Dealer ordered new part. Same problem. Soft foot makes clutch fall to floor without pressure to pop up. 
18000 mi Weak clutch, required pumping pedal. Slave cyl rebuilt. 
13000 mi The clutch pedal would grab high, low, then stay enguaged, then a popping noise and the clutch pedal went to the floor with fluid coming out of the transmission.  I had the car for 13 miles and the same condition came back, stopped working on my home street, had the service manager come out and confirm, and needed to be towed again.  Replaced some valve (Service advisor said they didn't know what it was) in the clutch system and replaced the slave cylinder again. At this point it was irrelevant,the car is unreliable. Hyundai and dealer refuse to work on the car anymore, I'm Stuck.
