Ok, just swapped out diffrent transmission that worked, the trans is an a440f in a 1991 lc. The problem I'm having is I get no response out of the trans in the normal high select on transfercase! When I shift to 4-low the trans will ingage, shift and move great and it also works when I push the center diff-lock button. Everything seems to be plugged in, has correct fluid and amount. What am I missing?
