Hi Guys. I want to use an external spin on filter and external cooler on my 200 4R. I need to know the direction of flow to and from the transmission to the external filter and cooler. It would be nice to see a flow diagram of all the components. Also not sure which trans line is the flow and which is the return. I don't think it matters much for the external cooler; but the filter has to be installed in the right direction. Any help would be appreciated. Thanks in advance Ed
