93 Topaz won't shift out of first?

My daughters 93 topaz will not shift out of first gear. The trans was rebuilt 2 yrs ago so I don't think its an internal trans problem. Does anyone know if some kind of sensor or vacuum module will cause this. My son called a couple of local dealers and they told him it sounded like a problem with some sort of governor, anyone got any ideas? Thanks

I am having the same problem, with mine and it is the gear inside the transmisson that guides the govenor gear. whole transmission is out having the gear replaced and broken motor mounts
