I do not know why you did not notice. We'll... there was nothing there to notice... for 6 years and over 20,000 miles of travel I've been very aware that the gear display had a "5", on the bottom and I watched as the the top number stepped through 1,2,3,4,5 until both numbers showed "5". Please understand that I'm tickled that it's now showing 6 gears. My whole purpose in this was to see if anyone had seen anything like this and more importantly, could this be something I needed to be concerned about. I'm guessing that the consensus would be that I needn't be concerned.Re: Workhorse Allison Jumped from 5 to 6 Speed (on its own)We purchased the 2010 coach in 2011 and have used it several times a year ever since. It is indeed a "W" chassis and not a "P". It was sold as having a 5-speed and has performed as such fo 6+ years. The dash display has always shown a "5" as the highest gear when in the "D" drive position. I never really thought much about the 5-speed/6-speed issue or differences over the years but was aware of the discussions on the forums about making the change from 5 to 6 speeds. I will say that I've always noted that the transmission seems to subtly shift twice in 2nd gear but never sought to see if this was true or my imagination.Re: Workhorse Allison Jumped from 5 to 6 Speed (on its own) wallynm wrote: What does the tac say?

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).
