    First time using site and could use a little help. I bought a fairly used up 1999 F 350 4x4 with a brand new Western Wide Out plow and auto trans. Fixed a few charging problems and exhaust leaks and we are up and plowing.
    My question is that transmission will not upshift out of low with transfer case in low range. It shifts fine in 4 high or 2 high. I have owned and still own several GM 4x4s that shift up while in low range. I thought maybe the Wide Out wiring somehow limits the shifting or maybe it has another issue.
    Any help would be appreciated.
