Default Tranny Cooler Lines

I've got an aftermarket valve body in my transmission that up'ed the line pressure...And one of the quick disconnects blew on me.

Temp. have dishwasher hose and a barb piecing it back together to get it home.

Does anyone make a good set of aftermarket lines or even the quick disconnects? I'm thrashing factory lines.

I got rid of my factory lines as well. I work at a Deere dealership, and I had them make up 1/2" hoses with 1/2" (-8) JIC fittings on them. That's what I am running now. Needed to make some pipe to JIC fittings to adapt what comes out of the transmission, but that wasn't too bad at all. I didn't spend $100 on the entire setup. I cut the hose to the cooler and installed a barbed/JIC fitting and hose clamps.

Well this brings my attention to the above.What is the line pressure at idle and at WOT?Both of my trucks have aftermarket TBs ect with stock lines. I Know that the idle line pressure is 98 PSI and the WOT pressure is 150 PSI. Maybe I should change to some GOOD S.S. Nonburst lines.

My quick connects started leaking as well, and that's the main reason I tossed them. The hose I am using is rated for 600PSI, and has a cotton braid in it, not metal wire. Makes them very easy to work with.
