Trans Cooling Line

[Pravus]

I recently got a 93 Corolla LE, been fixing alot of random stuff wrong with it as is sat for a few years before I took it on. My most recent problem has been losing trans fluid, eventually I figured out it's leaking from the Pressure side of the cooling hose.
It goes Trans>Pipe>Hose>Radiator, the entire bottom of the pipe section is totally rotted out and rusting, I am assuming this is largely the problem. I tried to put a new hose clamp on and /at best/ it slowed the leaking slightly.
So my potential fix and question of how good of an idea it is, I plan to cut the pipe with a pipe cutter around where the clamp is holding the pressure and return pipes together (maybe 4-5 inches up the pipe), then get a new section of hose and use a hose clamp up there and replacing the old hose all the way to the radiator. More or less shortening the pipe section by a handful of inches and lengthening the hose section by the same.

So the questions are is there any reason I shouldn't do this? anyone tried this and have any tips on getting this to work well (my main concern is the ridge used to help keep the hose on, but i was thinking I may be able to flare the pipe out a little)? and lastly I am 90% sure that the hose is 1/4" ID but I assume this based of measurements on a very corroded pipe, does anyone randomly offhand know the actual ID of the hose?
With hope I was clear on what I was trying to say..

Unhh, NO.

Delete what you call the pipe and just run hose rated for oil from the trans to the radiator. Because of the poor condition hose and pipe you may want to also do a filter change.

I had thought about getting rid of the pipe completely as well, but I wasn't sure what kinda parts where available with the connections needed.. Still lookin at various parts.

just replace the hose, don't cut any pipe lol, theres not alot of pressure on the hose

WRONG! Either replace the rusty pipe or delete it.

You dont want it to either BREAK or leave rust particles in your transmission.

Those hose clamps look nice.. thing I hate about most of the screw on hose clamps is they really eat up hoses and tear into them..
What I am going to end up doing once I get a decent day to work on it is pull the old hose off and sand down the pipe so it's remotely smooth, then I got new hose I'm going to throw on.. That is my temp fix until I can take the pipe off and see if I can't find a hose barb that will fit in place of the pipe, with hope it will stop leaking quite as much..
Although I suppose if the pipe is too far gone I will just pull it off then figure out the hose barb then and there..
