Rob Posted June 14, 2007 Share Posted June 14, 2007 I'm getting ready to swap out my two stick six speed for a Roadranger 13 speed (RTO12513) and don't want to use the Mack transmission as a core if someone may be able to use it. I don't really feel the Mack trans would work well behind my Detroit engine too well. The donor transmission is from a Mack Superliner and will be complete with everything needed for the swap. There is nothing wrong with the Mack transmission that I know of other than the shifter assemblies could use a little "tightening up" but is very useable as is and does not howl, or hop out of any gears.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
