Ok this morning i got in my car to move it and it started jumping on take off, shifting though the gears it was mildly smooth, but the clutch petal was vibrating, later after that while in 1st, the clutch gave out for a sec, then reengaged, now it wont let me shift gears at all, its not slipping at all, im assuming its something that makes it engage, release bearing, Do i need a new clutch or do i need to replace the release bearing? how much will it cost to drop the tranny, and who can do it quick?

Also if i replace the clutch do i need a new flywheel too, or do i just need it serviced?
