That is the trans cooler line.. Its hooking up to the intercooler heat exchanger
Check your trans fluid.. if its leaking then you are low..

It's the transmission cooler line to the radiator. If it's leaking and you have "bogging" you better check the transmission fluid level (hot fluid).
Here's a graphic that shows the cooler lines.

I see that you have a '96 XJ - correct? And that the disconnect has two yellow release tabs. You have to squeeze the two plastic tabs together while pulling the hose fitting off. Similar to releasing the tube from the adaptors at the transmission. See the pic.

Those things are hideous. I cut them off and just use hose clamps. Just as reliable and a lot less hassle.
