So seeings how that hose has a working pressure of 15 bar (roughly 220psi), it should be fine from a pressure standpoint.
I would be concerned, though, with how compatible the rubber is with ATF- seeigs how it isn't listed in the spec. I would THINK that if the hose could withstand both gasoline and diesel fuel... then it should be ok with ATF. But that's only a guess.
I'll have to revise my opinion here now that new info has come to light. In your situation, I would go ahead and install that hose... then just keep and eye on it. Make sure it doesn't turn hard or squishy.
That's exactly my stance on it.
FWIW, I've been running Goodyear fuel injection hose for the TL's cooler for 2.5 years and no issues. I check it whenever the hood is up, especially at the ends to check for mushiness. Originally I was going to make steel lines and did the rubber as a temporary alternative and 2.5 years later I still haven't gotten around to it. It does seem to be in excellent shape.
I also use the "fuel injection" clamps that apply equal pressure around the hose and seem to have a little more force. I double them up on every end.
