I'm currently running a 4.8 with a COS3. If i want to install a 4L80E is this the correct way to do the segment swap?
1.Use file from a 6.0/4L80E that has the same O/S as my original stock file.
2.Upgrade that 6.0 file to the COS3 so it has the same matching O/S as my current tune file.
3.Segment swap the Trans into my current tune
