Thanks for the answer, and that tells me a lot actually, but, I was referring to the bushing in the front pump assembly, the one the torque converter hub fits into for engagement of pump operation. I was told it was staked to the inside of the pump housing on the back side, hence, the reason for having to remove the pump. Also, transmission housing needs to be vertical as I was told to keep certain small parts like spacers and so on from moving around or maybe falling out of alignment when you pull the pump for this procedure.
