"Clutch slipping, but does drive"

"the car can be driven... the clutch's release bearing is faulty hence replacement of the whole kit"

"Clucth has a bit of a shudder, gears are chnaging fine, but a shudder on pull away"

"Does not always engage into gear, as if gear slips, especially when you pull away - it suddenly jumps forward, engine revs up (should be a gradual move forward, not a jump)"

"The clutch just need to be tough slightly to go in gear, Yesterday I get a smell like clutch burn, and when I drive and change gear the reffs go up and car not moving faster."
