Ok, What have I done now... (904 problem?)

Make sure your filter & spacer are properly seated & sealed to the valve body. If there is any gaps in it the pump cannot pick up the fluid correctly & it will cause the fluid to cavitate(suck air) as it goes into the VB & through the pump causing loss in pressure. Low pressure = lazy shifts.

I think for peace of mind I'm gonna drop the fluid tonight and take a look at that filter... Can't get serious with it until the weekend anyway so I'll look into it... maybe I'll get lucky.

As far as sealing it to the VB, there's a gasket there right? I seam to remember a real POS looking gasket, it looked like wax paper or something. What should be there?
