Coach has a Rockwell rear end with 3:55 ratio. Gearing is perfect and 2300 RPM = approx 78 MPH (depends on the wind). Here is a caviet - our Allison transmission is a 5 speed with a locking torque converter which actually acts and shifts like an additional gear (6 speed). If your new transmission does not utilize a locking torque converter, you will need a higher ratio. Newell should be able to make a recommendation. Hope this helps a little.
