bobandpam Report post Posted March 24, 2017 I've got an 06 Beaver Monterey Ventura IV. The Alladin system shows a "5L" or "6L" when I'm in those gears. It also shows a "2C" when I'm in that gear. What do the letters mean? Is there a low and high gear for the Allison transmission that I don't know about? Share this post Link to post Share on other sites
