There is a spot right on the frame rail on the Drivers Side that you can run the lines down from the transmission all the way to the radiator support so you can get them out of that area. I pulled the brake line down from the frame that comes of the distribution block to the left caliper and made more room there for them to squeeze by. I am not done with mine yet but I will post pictures after it is. You will be able to see them on my 73 Scamp thread in my signature.
One thing you don't want is a leak and a transmission fluid fire. That stuff burns hotter than Fuel and would not be a good thing.
