Setrab oil cooler for Trans

GMB14U2NV

Since mine is arriving tomorrow I haven't mounted yet. But this weekend I will look into the front end and see if I can mount it sideways. I think you were thinking the same thing when I started mentally designing the car add ons. IMO it would be best to go sideways with the in port on top and out port on bottom.
My Oil cooler is on the drivers side and both lines are on the top. The in flow was routed to the outer most port and the out flow was routed from the center most port.

The trans cooler I was thinking kind of center to passenger side with hose ports pointed towards the passenger side. The cooler I have is a smidge smaller then most 19 row units I've seen. It should fit nicely between horn and PS cooler.
