Transmission cooler line leak

Discovered my transmission cooler line has a leak. See attached photos.
 

It appears to be in the rubber portion. Is there any way to repair the hose or do I need a completely new line?

Rust on the steel line is the most common failure point but the crimped on rubber hose is really just a sort of hose clamp. You may be able to salvage the assembly by removing the crimped sheet metal clamp, remove the damaged hose portion and reassemble with two new clamps 90*apart. The best is a crimped type clamp (Oetiker style)

My problem now is the line fitting that connects to the transmission itself seems to be seized? I’ve sprayed it liberally with PB blaster and let it sit with no luck. The other cooler line fitting comes right off. But this one doesn’t want to. Even tried vice grips. The fitting seems to be of a soft enough metal it won’t hold.

Using a tubing wrench might have got it loose but you are probably past that point now that you've used vice grips on it.

So this leaves me where?

I don't know how much room you have to work with. If you have room to get a small pipe wrench on the fitting it can apply more gripping pressure than vice grips. The harder you pull on the handle of a pipe wrench the tighter is squeezes the fitting or pipe in it's jaws.

If it requires that much pressure to remove it, you run the risk of hurting the fitting in the radiator. Is it the bottom one on the radiator. Not easy to access when everything is buttoned up so last ditch would be to pull the radiator with the line still attached so you can get best access, or do the line repair.

I agree with that. I guess I misunderstood. I thought he was talking about the fitting that screws into the transmission.

I believe you are correct. I reread the post about the seized fitting and it is indeed transmission. My bad

Yes I was referring to the transmission fitting. I was able to get it out. Turns out I was correct using vice grips, I just forgot to add the use of a hammer with said vice grips. 
 

I got the hose out and had a local shop repair the hose for $20.
