Default Question about line pressure at idle..

Hey guys,
I just installed a new trainy and stall in my car and decided to Atap it today. I noticed that when I have the car in drive and the brake on, Atap says there is 0 line pressure. As soon as I give it gas the the line pressure goes up. The car does not have any slippage at all. When I installed it I put a total of 9 qrts of trainy fluid in it and I don't trust the dip stick because of inaccurate levels. The trainy has a deep dish pan (3qrts) and a trainy cooler which I figure is around 1/2 qrt. So should I be having line pressure while I am not moving? Any help would be appreciated. Like I said, the trainy seems to be fine and the temps are staying very low. Thanks. Timmay!!!

There are tables in the PCM that look like they are
zeroing line pressure in P and N. You could make
them nonzero but I can't think of a good reason
why.

Thanks Jimmy. The pressure is also zero if the car is in drive with the brake on. Should I be reading pressure? Timmay!!!
