The clutch is actually in the drivetrain. It's 2 shoes that spin out from the driveshaft and engage on the clutch bell (it's a hollow cylinder that they catch the inside of). If it's worn out, the clutch shoes are melted and they're stuck to the inside of the cylinder or something along those lines. You'll have to take the engine out, and just remove the drivetrain up to the engine, it's about 3/4 of the way down the line to the engine.

The 2 speed tranny is seperate from the clutch.
