I recently got my transmission swapped with another used Awd trans same year. Kept great communication with the mechanic while getting the trans. He let me know ahead of time I’ll need a flash after the replacement. Finally got it replaced and went to Infiniti to find out they don’t have any programs available to flash my car. My car is in slip right now after the replacement. Why would my car be in slip after a swap? Does a reprogram have anything to do with that? Or maybe did the labor of the transmission mess something up. Also, why wouldn’t Infiniti have any programs to flash my transmission.
