Transmission cooler lines from 4L60E - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What are you guys doing for transmission cooler lines on the 4L60E? My preference is the good 'ole 5/16" hard line, but the fittings are not the same NPT thread where they screw into the transmission. I'm not looking to convert to AN and run braided lines, not my thing. Is my best option to buy the dies to be able to duplicate the GM flare on some hard lines and run the OEM fittings in the tranny? I do have the Mastercool flare tool so I think this is an option for me. Are there fittings available to just use double flared lines?

Thanks!
