Use of SAE 15W40 motor oil in Allison HT746
« on: Today at 03:49:28 PM »
I just got some quotes on 34 quarts of Dexron III ATF for a transmission fluid change. I didn't like what I heard. I looked up what Allsion specs and it appears if I read it correctly that I can use SAE 15W40 motor oil instead of ATF at 1/4 of the cost. Has anyone done this successfully? Do you have any comments?

The guy is coming tomorrow to do the oil change so a quick answer would be appreciated.
