I recently took out the old rusted oil cooler lines for the transmission but I made the mistake of forgetting which lines hooks up the the cooler where. Does anyone know which hole (front or back) is for what line on the cooler?

 

I'm not sure, but I don't think it really matters. Just which ever way it fits the best for good air flow. In theroy, it still goes through the cooler either up or down. That is unless there is a check valve that prevents backflow. You could check for that and if none then I'd guess it dosen't make a difference.

 

Thanks, I hooked them up and everything seems to be working ok.
