I'm confused. If the wheel un-locked when you pulled in the clutch, the problem has to be in the engine or the clutch itself. The wheel is always connected to the trans gears, even with the clutch pulled in.
Mine did the same the first time...about a 10 metre skid mark at 120kmh then she freed up then locked again for a bit then freed again. By the time i coasted to a stop it would only move in 5th - she would locked in the first 4.
On the plus side i learned a tocket will climb a ramp in 5th with enough revs and some clutch work
