Hello all, I’m a newb here with a couple of questions on transmission lines.

I have a 2003 Grand Prix GT, the lower line from trans to radiator is leaking. I’ve been trying to find replacements, but it seems they’re a dealer only item.

But my first problem is how to remove the lines from the radiator.
Do I need a special tool or do I just remove the whole fitting from the radiator?
Once I have the lines off, should I use factory replacements ($$$$), or go with some ideas I have gotten from the ‘Trans Cooler’ thread? (A/N to tubing, and hoses).

Part of me says to just cut out the rubber sections/crimp fittings and replace with reinforced braided hose and 2 clamps on each end.

Is this a safe option, as I don’t know how high the line pressure gets, is there a chance of the line blowing off of the tubing sections, even though I will use two clamps and possibly flare each end of tubing?

Any help out there ??????? LOL.
