Ok, I have bad news, Well its not horrible but its not what you want to hear. your transmission needs to be programmed. The reason is this, the value body had inside it the transmission module and when you replaced that transmission, you replaced the module as well. The module needs to be programmed to the VIN of the vehicle to work, otherwise its brain dead if you will. This programming can only be done by a shop, and usually GM dealers or very well equipped shops can do this.
