I have an 03 denali and looking to swap out the transmission, 4l65e, and transfer case, bw4481, to 4l80e and possibly 261HD or 263HD. I understand for the 261, I am going to need the shifter cable and a shifter. However, if i look at the 263HD, I'll need the harness, panel, and possibly a reprogrammed TCCM from the vehicle i got the transfer case, is this correct?
Anyone experience doing this? I currently have the 4L80E, crossmember, and driveshaft from an 02 Suburban.
