Check the wiring harness going to the transmission sounds like it may have come loose from the holding clamps and maybe got caught in the exhaust. If the wiring looks ok check the plug's on the transmission if they look ok its time to go inside the transmission.

Could this be the Transmission Control Module Computer????
