You said you lost some fluids and replaced them? from my experience with Allison transmissions if they get "hot" they go into a self protect mode. I would try shutting everything off if your in a safe location. Like kill the motor. Let it sit for 30 minutes to cool and try it again. I've had to do this with military truck with a Detroit 60 and Allison combo. Allison transmissions have many many safety features most are unaware of.

Im in Alaska so ill be up for a bit

By chance were any of the brakes warm when it quit on you? Air pressure holding steady?
