Re: who knows their allison transmissions???
i can hear/feel the trans shift from first to 4th gear. I found the axle ratio, and the tire size is easy enough to come by as well as max rpm for a 6v71
max rpm: 2350
axle rato: 4.56:1
tire height: 41.3 inches
final drive ratio: 1:1
max speed 63.34
unless that trans has overdrive which is very unlikely, someone is not telling the truth when he states it'll cruise an indicated 70 or 75 mph on the speedo which he believes to be an actual 80 -85 mph. I tested the speedo vs my gps and found the speedo to be off less than 4% ie: when speedo sais 50 mph the bus is moving almost 52 mph according to gps.
wonder how i can identify the transmission....perhaps i can find a tag on the unit when i crawl under there.
