hey guys, new to this whole thing so I apologize in advance .
did a 4l80 swap in a RCSB Silverado 1500 that came with a 4l60
getting codes from the 4l60 still so im guessing I didn't get the segment swap done correctly, any information would be amazing. and again im new to not only HP tuners but Forms in general so anything I left out that you need please feel free to ask.
Thanks in advance
