right now I am rebuilding the transmission b4ra and I notice one ATF feed pipe with screen on the end. just wonder this screen end should face up or down and which valve it should go to. I know it has to be on main valve or secondary valve. the item on the diagram for both valves is #1 on hodna estore and both have the same catalog number. thanks

 

Did you check in the service manual?

 

can not see that from service manual. none of them has been marked.
