6 speed manual. Clutch repair issues........ on 2004 Chrysler Crossfire

I have a 2004 Chrysler Crossfire. Six speed manual.....Clutch slave failed. Had my mechanic replace clutch pressure plate, bearing, clutch disc and slave cylinder. He put everything together, bled the system and all seemed repaired. Drove car about 5 miles and clutch went to the floor and had to be pulled up manually. Gears would no longer engage.....Stopped on the side of the road. Burned fluid smell....Mechanic installed another new slave cylinder, bled the system. Clutch pedal appears to have pressure when the engine is off. Once started pedal goes to floor and won't engage transmission. Appears to have no pressure. He is stumped. Does anybody have a clue what the problem is? HELP!!!!!!

Sounds like you may need a master cylinder.

Burned fluid smell. Opened transmission and found new slave cylinder leaking. Mechanic blames aftermarket Non-Mercedes part. I have purchased a new master clutch slave and a new FTE (same as Mercedes OEM unit for him to install. We will see what happens........Will let you know. Robert

One other thing to make sure that you are using brake fluid when you refill the clutch fluid. Specs call for DOT4 brake fluid. No question we have had various issues and problems with aftermarket replacement parts. OE replacement could be a problem with the fact that a part that has rubber seals that can go bad sitting on a shelf in a wearhouse that is not climate controlled.
