F455594 Report post Posted March 15, 2017 I have a 2006 Coachman Cross Country 38DS. Went to move it yesterday and as soon as I started it the "Shut Down" and "Check Transmission" warnings came on and did not go off. I shut down, but, what do I do now?

wolfe10 Report post Posted March 15, 2017 F455594, Welcome to the FMCA Forum. First suspect is low battery. Electronic devices throw all kinds of codes when operating on low voltage. So, what is voltage at the chassis battery? And, with the Allison transmission, you can check for diagnostic codes from the driver's seat: Ignition on, engine off. Push up and down arrows at the same time. Repeat. That will bring up d-1, then either - - if no diagnostic code or a two digit code if there is a problem. If there is a d-1, push the mode button to bring up d-2. Continue until you get a - -. Turn off ignition and look up the codes in your Allison owners manual or Allison on-line.

hermanmullins Report post Posted March 16, 2017 Could low transmission fluid cause the same warning? Herman Share this post Link to post Share on other sites
