Apparently this happens a lot with the transtop (it gets stuck). Unfortunately, US sols don't have the transtop option, so I don't know a whole lot about it. I know the gears wear out and break QUITE easily (I think they're made of plastic) Do a forum search for a member named "mariejader". That member has a shop in Ireland I believe that specializes in servicing transtops. They might be able to give you some answers. Sorry I can't help more!
