Landyachters Report post Posted August 17, 2013 We started off today on our first venture and our transmission is showing the check transmission light and it won 't come out of first gear. Any ideas. It is. 2004 Monaco Dynasty. Share this post Link to post Share on other sites
wolfe10 Report post Posted August 17, 2013 Assume you have the Allison 3000 series transmission. If so, pull out your transmission owners manual and, using the shift pad, check for codes. Very easy with engine off, ignition on. You will push the up and down arrows at the same time TWICE (first push brings up fluid level which can not be checked unless transmission is up to operating temperature and running). Second push of both up and down arrow begins the diagnostic codes. You will have d-1 and then a two sequence code. If no codes, it will show d-1 - - . If there is a d-1, after you record the code, push the Mode button to bring up d-2. Continue to record/push Mode until d- whatever - - comes up. If you don't have the book , let us know the codes and we can look them up for you. Brett Share this post Link to post Share on other sites
desertdeals69 Report post Posted August 17, 2013 I had that happen to me and I stopped and pushed the disconnect switch for the chassis battery and then pushed it again to turn it back on and everything was ok. Share this post Link to post Share on other sites
