The trans has to come apart ....but if you want to verify,you could pull the valve body and seperator plate out ,since the pan is off,and air check the circuits..might be a bit messy with trans fluid up in the trans tho...let it drain for a while after
vb is out..rev is the port just next to the servo cover....forward and direct [3rd gear] ports are on either side of the center support bolt....shoot a quick short blast of air into them...a faint but solid thud should be heard when air is put to them....... and flow charts are prob out there on the net somewhere.I allways just referenced my trans shop manuals for them.
