Path1,
I have 2 needles on the gauge. One red and one green. Both move together. Owners manual says that one needle is for the front tank and one is for the rear tank. I'm getting 120 PSI on the air gauge so the pressure is good. Can't figure out why the alarm comes back on when I put the transmission into Drive?
I am not used to separate needles for separate tanks. So I'm probably not much good to you. But did find this article, not sure if it will help.

Great article. I had actually done some of those tests and the brake system seems in really good shape. The warning alarm when I put the trans in DRIVE has got to be something else. That's why I thought it was an Allison alarm but no one can tell me. Not even Allison.
