904 oil pump passages

Looks like I'm not the only one here having problems with my 904 !
I see and hear a couple of people seeking informations for shifts problems.

Before I go and look for answers, I need to know what does what and where....

I tried to look for schematics on the oil pressure routing going out of the pump where they go and for what purpose.

A description of the holes around the oil pump

Where can I find infos and drawings on that ?

I have a 72 Chry/Ply Service manual, and it has a few pages of fluid flow thru the trans in different valve positions.

Ok...

Using the air test diagram below you can blow air through the labeled case passages and feel where the air exits the case with the pump removed...match the ports in the case to the openings in the pump body.
