could it be the valve body that is in need of replacement

First thing I''d suspect is an electrical porblem is this happened all of a suddr. Either a battery or alternator problem. If not that then the valvebody in the transmission may be bad. But those usually go out over the course of a few months or years.

I agree. Check all the fuses related to the transmission/transaxle ...
