The TCM is in the box in the passenger rear side of the engine bay.  There are 4 screws holding the cover down and there are 2 circuit boards housed inside.

All i can give you is a good place to start. The transmission control module- It is behind the bottom panel that houses the speaker on the passenger side (by your feet) it could be loose or it could be shorted. Also check if there is an aftermarket security system. These mess with the whole electrical system.
