    Hi Allisonman,
    I have a 2000 HR Endeavor motorhome with a Cat engine and Allison 3060 transmission. While traveling this winter, I noticed that every time that I put the cruise control on, the transmission would downshift to fifth gear and run for about 30 seconds and then shift back in sixth gear. Later the transmission downshifted while going down a slight grade, even though the exhaust brake was not on. What do you think, do I need to see an Allison repair center?
