Can you??
 

Im woundering if i can replace part of this line with a good rubber one does anyone know or is there to much pressure or something??or by pass it or something? Whats it for exactly?

Factory transmission, or mild build, you will only have about 100psi max in the lines. A weel built will have up to 300psi in certain situations. You could cut the bad piece out, add rubber hose, and use at least 2 hose clamps per end.

Ideally you would want to splice the line with metal lines

Did you find a cracked line, is that why you are thinking of splicing?

You can get hydraulic soft line to replace the metal ones. I am sure you can even put those male fittings on it too.

My entire hose system for my trans cooling is 5/8" hydraulic hose with JIC ends. It is excessive, but it was readily available to me.

Or u can use hydraulic line like stated. But just using rubber line and hose clamps, I'm not a fan of that

As non-ideal as it is, it is the way the factory cooler is connected to the system.
