Ok been searching for this. Know I have read about it on here but can't seem to locate it. Took pioneer up town this morning and can't get it out of 2wd. Was going to put it in turf mode and it wouldn't change. Shifter seems to be working fine but light on dash says 2wd and it is. Turned corner in gravel and it's definitely still in 2wd. Any suggestions on linkage adjustment or?
