billnm Posted January 5, 2018 Share Posted January 5, 2018 I was watching these videos on youtube where these guys have swapped in Eaton and Fuller 9 and ten speed transmissions into there 1 ton trucks behind newer Cummins 5.9 L engines. I would have never thought of such a thing! How hard ( or impossible) would it be to do the but instead of a 9 speed Road Ranger, one swapped in a Mack Duplex or Triplex or even a quadraplex? I just think, why not, it might be fun! What do you think? might be fun! Quote Link to comment Share on other sites More sharing options...
j hancock Posted January 5, 2018 Share Posted January 5, 2018 You can do anything you want. I wouldn't bother. Not to say that a Fuller (or whatever brand) is a light transmission but a Mack Duplex/Triplex/Quad box weighs a LOT. So, after you spend a bunch of money for the conversion and buying all the parts needed and custom fabrication ($$$$$), your pickup will be about 2,000 lbs heavier. For the same money spent on conversion, you could buy a Mack B, L or R hobby truck and do some two stick shifting. 1 Quote JimIt doesn't cost anything to pay attention.

HeavyGunner Posted January 5, 2018 Share Posted January 5, 2018 (edited) Or you could do a gear vendor over drive which would double the amount of gears you have without doing a big conversion or adding hardly any weight. I know a guy who has one in a 93 dodge with a 12valve in it. He loves it.
