Passing trans lines thru cross member.

I am always open to this sort of information. My Transmission was built by a local guy me and my dad have always used. It is just a stock 727 out of a c-body. It has the cheetah forward pattern manual valve body with the upgraded servo arm. It is pretty much a stock rebuild other then that. I was just going by what i though was right. I have always read and heard that heat is what kills a trans. my thinking was that with the high stall speed on the street i would be creating alot of heat. then when i decided i wanted to hide the cooler and mount them out back i thought i would make up for the air flow with a larger cooling area. who knows i may have way too much cooler or not enough. either way i will be learning what works for my car. its only money right? ha ha ha
How far are you from getting your ride on the road? Be interesting to see how well your coolers work with no fan or air flow. I am planning on pretty much copying your set up, hope you don't mind. Saved the pictures just to remind myself. Friend that will be building my trans would probably put a bullet in me if I did not put a cooler in my car. Heat is indeed lethal to a trans. My diesel truck has 2 coolers in it, the radiator, one in front of the intercooler and one under the truck by the fuel tank. When towing in the desert if I could not get the convertor to lock up I would see 230* or so. With the expense of of trans stuff I can not imagine not running a cooler, but to each there own. Fluidyne db 30613 was the one that I used on a truck project a while back. Had it mounted on the cage up in the wind and worked well.....
