1989 Jeep Cherokee Transmission Cooler Line Leak

I want to replace the transmission cooler line from the hard line to the radiator.

This is "the flex line" that interfaces the moving engine / transmission / power train to the rigid and fixed cooling system. ( so the dern thang does not fall apart with motion )

I do not like their cheap "quick connect" design, which allows them to have a faster assembly line, but is poor engineering as it degrades and starts to leak with age at the O rings.

I thought about just sawing it off, but instead "can I / should I " REMOVE THE LINE ( which needs a tool that I do not have ) and then just slide the 3 / 8 inch transmission oil cooler line OVER THE CONNECTOR ?

My problem is I cannot find a direct and NEW replacement for that part and a used one may be just as defective.

What do you recommend ?

1) Saw off the connector and try to connect over the "nub" ( only one connectors width to work with )

2) Try to remove the connector EVEN IF I DAMAGE IT, and slide the line over the connector.

I hope to use two steel banded adjustable clamps on each end to hold the NEW 3/8 flex line on.

I do not have the money to have it done by a real mechanic.

ALL ANSWERS WELCOMED !

( some of you "do it yer selfers " have done this )

Please advise,
