904 trans pump question

Which is why I never put fluid in the suckers until after it is installed, cuz it just runs out somewhere .........lol.
The clutches get soaked and all else get lubricated, but that is all she gets.
Install it,including the driveshaft and speed-O, fill the convertor, start it up in park , let her run for a half a minute, shift her thru the gears, then top up as may be required.
BTW
AFAIK only the 727s got the shield. I don't remember if any of my passenger-car 904s ever had a shield. Just don't know.
