904 Transmission issues.

Well today I pulled the rear line off to see if the pump was pumping fluid,no fluid pumping.Now I had pulled the shifter cable off pryer to checking,so it was in park.Will the pump still pump fluid in park?Or does it have to be in nuetral or drive?Thanks for any help.:read2:

P.S Looks like I,ll be pulling the tranny after the long weekend.Yeahhh hoooo.
