I don't want to discourage anyone from doing something new, but my
understanding, limited as it is, about two speed rear ends and the m35
transfer case leads me to the following conclusion:
With a two speed rear end I think the gear ratios are much closer than the
difference between the high and low of the transfer case. I have never
tried to use the transfer case to achieve a selection of gear ratios
because, unlike the trucks I have used with the two speed rear, you would
have to shift the transmission to a different gear each time you shifted the
transfer. When using the 2 speed rears, for example, you shift from 1st
gear high to 2nd gear low, then to 2nd gear high. If I understand the tag
on the dash of my deuce, if you have the transfer in low range 5th gear, you
would have to shift to 4th (?) high, then to 5th high. Am I missing
something? Just something to think about.
