Need a quick solution to shortening transmission cooler lines

1995 940 Turbo with the transmission cooler in the radiator. A few years ago I moved the radiator a few inches towards the rear of the car to fit a bigger intercooler. I had to shorten the hard metal lines that run from the transmission to the radiator so I cut about 4 inches out of each and clamped a short piece of flexible rubber hose in each line. That rubber hose finally deteriorated a few months ago and I've been replacing them but they keep failing.

I need a good solution to this problem. I don't have the means to braise or solder the pipes shorter or anything. I just want a type of hose that I can get soon that will hold up to the task. Part of the problem is the rubber hose fits in where the line curves so I think the cut metal line is cutting the inside.
 
Go to auto parts store and get some transcooler hose. Hoses last 4+ years without issues with hose clamps.


And use semi proper tools to clean up the metal hose ends so they do not damage the new hose.
 
Here's the best picture I have.

I'll try and do a better job cleaning up the metal hose ends. I sanded the sharp ends down before. I'm not sure if it's cutting the hose from the metal hose end or from the worm hose clamps. Would fuel hose clamps work better?
 
The ones on my Toyota (has flex hoses) are 25 years old and original.

*shrug*. They have proper barbs and a heat shield.

Or get a flare fitting and flaring tool and splice them metal/metal.
 
I "rented" a double flaring tool from autozone to put a flare on the end of the lines when I hooked up my power steering to the trans cooler. This gave it a little bump on the end to keep the hose from sliding off and dulled the end of the line too. I think the 8mm metric one fit a little better than the 5/16" sae one, as I rented both since I didn't know whether the line was metric or not.
 
So I've been googling it and it seems flaring the end of the metal line and two hose clamps on either end of rubber transmission hose works well.
On the radiator side, does anyone know the thread size of each fitting that goes into the radiator? I'll just put a hose barb to attach the rubber hose to there.
 
I meant with regards to ps and trans sharing a cooler?

Or a trans cooler being used for the ps separately?

If sharing, one wonders how proper fluid level is maintained in trans and power steering circuit?
 
Put a single flare on the end of each line and new hose. The box for the hose said fuel/emissions on it and I asked the guy at least three times if it was rated for ATF but I still have my doubts so that will get replaced soon.
 
Power Steering ReturnHose would work....................P/S uses ATF.........
 
And what is the psi rating on trans cooler lines? I'd guess that it far exceeds the pressure rating of gas hose. I never had any luck the first time I tried using gas hose on a trans line either.
