It won't hurt anything. It's a step in the right direction and way better than the original oil at 100%. You won't hurt anything to run it that way, and next time you can change it the same way and have a higher ratio. The other option is to keep an eye out for transmission specials at the Allison dealer as they run them for a full flush and Transynd fill. I know some people who know some people in that field and will see what I can find out next time I talk to them.
