Default More Transmission Problems HELP!

I posted a thread on here recently with a transmission problem. I'm swapping an LS1 with a 4L60E into my 1977 corvette and I keep blowing out the line going from the tranny to the transmission cooler. First I thought the problem was a clogged vent line on top of the transmission, so I unclogged it and put another 8 quarts of fluid in, only to have the line blow out a second time on me. So then I thought it could be a clog in the tranny cooler so I've bypassed that and just made a loop, with a pressure gauge so I can see what's going on... I'm STILL getting a steady 20 PSI in P,N,4,3,2,1; and almost 40 PSI in R. I'm pretty sure these lines aren't supposed to see this kind of pressure, right? Also, as far as I can tell the lines are just friction fit in, is there some kind of bracket that's supposed to hold them in? I'm completely at a loss here and I'm so ready to have this thing on the road. Thanks.

20 and 40 psi is well within normal range on the inlet side of the cooler. You have to remember that its not a dump its fed back through restrictive holes to bushngs and planets.
Presures can reach 80 psi at MAX LINE ,
