Repairing my transmission cooler line

[bigjay]

We'll, it looks like my transmission cooler line is seeping VERY slowly( takes a week to almost build up a drip). My question is, I've been reading about diy repairs. It's weeping where it's crimped to the rubber section. I went and bought 3/8id oil cooler line and some fuel injector clamps to do the repair. Question is really is has anyone on here had to do this repair and how well do y'all think it will hold up? How much pressure is these lines holding against? New lines are 150 from what I've been seeing online plus. I have the means to do the diy repair, so I could knock this s out in a couple hours. Any input or advice would be greatly appreciated. Thanks in advance

I just did mine two days ago so far everything is good and dry. But I’m keeping an eye on it.
So many have done this “diy” that it should be good.
Mine took about 45 minutes, cut the factory crimped clamps with a dremel and they popped right off with a screwdriver. Used 3/8” hose with FI clamps. But I’m considering changing to a slightly larger hose to get it over the factory ridges and clamp the other side of it. Seems like it might be more secure.
I also am trying to find out what the pressure is on these lines.
Good luck
