The vehicle is a 2003 Denali LQ4/4L60E with 12582605 hardware / 12579405 OS. I have a 2003 LQ4/4L80 with same part numbers to copy the segments from.

My question is, importing the transmission and transmission diagnostics modules/segments is obvious. Do I need to import the speedo segment as well, and then correct for gear and tire size?

Thanks in advance!
