did you take the variator off it when you rebuilt it?im not sure how far you went with your rebuild.if you have not done the nut up properly on the end of the variator it will not grip the belt and drive also it will strip the splines on the outer half of the variatorhave you checked the belt to make sure it isnt broken?either way you need to take the transmission cover off and have a look in there it should be obvious what the problem is when its off.
