I have a 2010 Bounder 33u on a Workhorse Chas is with Vortec 8.1 and Allison 5-speed (approx 26,000 miles). I've read that the 5-speed can be changed to a 6-speed but this is pretty strange. We've been on the road for several days and 2 days ago I noticed that the dash display is now showing 6 speeds. Also maybe my imagination but when it goes into the 6th speed, it's smoother and quieter (as if it's shifting into OD).
What actual Workhorse chassis do you have? If it's the "W" series I do believe all Allison transmissions that were installed from 2005 and up have the 6 speed transmission. Now if it's a "P" series chassis it may have something different.
