Hello. I have a 1999 thomas saftliner mvp with a cat 3126 engine and allison md3060 trans. IT is currently set to only 5 gears on the tranny and I'm hoping to get it reprogrammed to 6. My question is with the axle gear ratio at 5.40 will it be useless? I redline now at 66 mph. I don't want to go any faster I would just like to get the rpms lower when I'm on the highway but I don't know if the bus rpms will be high enough to get to sixth gear before 66mph. Hopefully so,done will have some insight on all of this. |
