Thats alot of pressure its true that its differnt from the other gm transmissions it was bulit for saturn like the engine in ur car. There pretty simple transmissions there basicially a manual trans with clutch packs. Now
to ur problem I have seen a filter blow off on those transmissions before. What regulates the pressure in them is a pressure regulator its located in upper valve body I have seen them stick or the spring break in them allow too much pressure to bulid. They use to sell a upper valve body kit by itself but now they make u by a whole valve body very expensive. Theres a company that sells the upper valve body and they say that there improved in the regulator department. Its www. Omegamachine. Com I just starting talking them about them. There under 200 the whole valve body is over 500 start with checking the pressure regulator let me know what u find.
