These are likely to result in failure. See, the factory lines are mostly hard line and are rigidly mounted to prevent movement of the fitting around the clip. When I did the 4l80e conversion in my truck, I cut a section out of the factory hard line to move them and then used rubber line to get it all connected back up (basically made the exact part your showing out of the factory hard line). Over time the movement of the rubber line allowed the fitting to wear out and it blew the pressure side out of the trans on the freeway which nearly burned my truck to the ground. And I had the rubber section of the lines zip tied to everything to keep this from happening. It lasted about 5000 miles before this happened.

Its a cool fitting and would certainly make for a cheap install, but in my opinion is not worth the risk. Either use factory lines or convert the fittings that go into the trans to -AN fittings.
