blakeloke Report post Posted September 13, 2016 Bill.....thanks for the tip. I finally registered on Cummins Quick Serve after getting our engine serial number. I couldn't fit my fat head in to find the serial number but found it on a Cummins West invoice. Joe.....you were right. Engine has a build date of 24 November 2004. Errr....day before Thanksgiving! Still awaiting word from Monaco on the chassis data. Blake Share this post Link to post Share on other sites
wildebill308 Report post Posted September 13, 2016 Blake. hear is a good source for information on your Allison transmission. http://www.allisontransmission.com/my-allison You will need your transmission serial number here two. I keep all my serial numbers handy in a file because when you talk to a parts place the first question they ask is "what is your serial number?"
