98 Z71 auto to manual trans swap, now ecm issues
Hello, new to the forum. I have a 98 Chevy Z71. Pulled out the 4L60e and put in a NV3500 and 32 spline transfer case. Just completed the swap, mechanicly everything is running good. Electrically my SES light is on and it is picking up 7 transmission codes. I read in another post that ecm needs re-flashed to manual program? Has anyone done this or figured out a way to get the ecm to stop reading the trans codes? If re-flashed is needed who can do it? Any help?
