I have a 2005 Winnebago Voyage on a Workhorse W22 chassis with the Allison 1000 transmission. The best I can tell from Workhorse is that the transmission was originally filled with non-synthetic fluid. I'm a little confused about the recommended service interval as well as the number of filters to be replaced at service. I'm also not sure whether we fall under general or severe use. My goal is to do the right thing, but I don't want to waste money either.
Appreciate the help,
