Hi Steven, My name is***** you replaced the shift controller does it power up now? What is the make and model of your transmission from the ID tag?
thanks for the update Check for an inline fuse between the battery box and TCM and test your fuses. Also inspect the wiring between the battery box and TCM. Let me know if you can get the model from the transmission tag so I can see what I have for diagrams
