allison 1000 transmission

driving an Itasca 34' class A MH in KY. MH is on a workhorse chassis w/ a 8.1 engine. I am towing a Chevy Equinox up and down the hills heading for the mtns. in TN. After several hours got a alert on our lcd display saying to "check transmission temp". I slowed down and took it easy for a few miles and it went away. Is this something to be concerned about and have checked? If so what could the problem(s) be?
Any info would be appreciated!!!!!!
  • Here
    Get one of these to verify the temp sensor is accurate. A quick click pointed @ the bottom of transmission will verify. Great item to have in the tool box.

    Where is the tow haul mode is it a switch??


    It is a button on the end of the shift lever on 3/4 and 1 ton PU. Not sure on your motorhome.
  • I have the 8.1 chev with a 1000 Allison in my MH and there is no tow haul button. The OD switch is on the dash. I don't believe the OP has a tow haul button on his MH.
