When the line blew off there was only one hose clamp on it, and up to that point I never had a leak issue. I have not blown off the lines since that day, so I dont think its a pressure problem, and like I said, I checked the cooler. The shift pressure was set back to stock when I got rid of the programmer.
I already bought the fittings and high pressure line to replace the metal lines, so Im waiting for time to do the TC and install the new lines when the trans is out.
Just for reference, here are the fittings and line I bought:
Male -6 AN to Male 3/8 in. NPT
90 Degree, -6 AN Hose Barb to Female -6 AN
Hose, Twist-Tite, Rubber, Blue, -6 AN, 20 ft.
