I'm using braided flex 6an from th400 to cooler. There are specific fittings that needs to be replaced on the trans to accommodate the braided flex. I haven't decided how to keep the hose separate yet. I'm also using 8an braided flex from fuel tank to pump. The cost really isn't in the hose, as braided flex is relatively inexpensive. You'll bear significant cost in fittings. By flex, I'm assuming it is braided stainless steel over rubber hose that encases a fluid resistant teflon inner hose.
