Either it has a bad modulator valve or internal pump may be weak.

Well just saying you have a Pontiac does not really help much with no year or type of transmission. Hell just a year and type of car would help narrow down possible problems other than that its just speculation on answers you get.

My Bentley Arnage had some transmission trouble. It's best just to replace the whole unit.
I got it in blue this time...

Probably its had it but check your transmission fluid w/engine running in park or neutral.
