Re: Trans. cooler lines
I used the factory hardlines and did not use any rubber hose. I mounted the tranny cooler below the radiator. I bought some union fittings that connect two bare lines at HomeDepot and made the cuts and bent a little and then joined the pieces I wanted to use with the fittings. NAPA also sells the same size metal line with the end fittings on them. I bought 2 12" pieces. You can bend them with a pipe bender and make it look good.
