I've never changed my Allison Tranny fluid or filter since my coach was new 12 years ago! I thought I read a post from Bumpy a few weeks ago that it should be done at 25,000 miles? I change my motor oil and filter every 10,000 miles or once a year.
I believe with the 1000MH transmission it was recommended that you change the screw on filter at 5000 miles and then again at 30,000 miles. The internal filter gets changed at overhaul.
Your transmission came with DexIII which does not last as long as Transynd. Transynd is what Allison recommends now for your transmission and it will extend your fluid change interval to more than double that of DexIII but it takes two changes to get all of the old DexIII out to use the new change interval.
I did notice that after I changed to Transynd that my transmission runs cooler in the Western mountains.
