It's real hard to get that seal in properly when the tranny is in the car. You probably just need to try another new seal and make sure that you get it in straight and to the correct depth. Then (stating the obvious) make sure that you don't bugger up the new seal when you insert the axle.
Frustrating, but a fairly straightforward problem as long as the opening where the tranny receives the seal has not been damaged.
