my mom and dad have a 2006 sequoia SR5 with all the toys and whistles including electronic actuated 4wd and low range. the issue is this: it will not shift on the fly from 2hi to 4hi. you have to stop place the auto in park or N wait about 15 sec and then only occasionally will it shift. most of the time you may have to move forward or back a couple of inches and retry the process. Is this transfer case not capable of shift on the fly? in this day in age i would certianlly think that it should/would be shift on the fly. i have tried to talk them into taking it back to toyota, but they won't as my dad seems to think that he is driving a 1950's/60's 4wd again. any thought?
