Hi ya
i saw a thing on TV years ago bout them i think the NZ army had just got them from what i can recall the gear box was 6 or 8 speed but had a lockup kinda deal the gears worked in a H pattern ie 1,2,3,4 only in 4 would 5,6 unlock and then 6 unlocked 7,8 same deal going back down 5 unlocked 4,3 and 3 unlocked 2,1 also had a time delay so ya could not drop down gears fast can not recall why tho ...there were 21 for sale a few months ago in NZ but i did not see what they sold for we had just got a big trailer and thinking bout it a unimog may have been a better deal
i think they may be pricey to fix tho
catch ya
