my question is there something I can put in line that I can relieve the pressure w/o taking it all apart?

A quick google search came up with this:

Come back in the early AM or on a cloudy day, and sometimes the locked fittings work like a charm...

You are most welcome

I remembered reading about those in the Farm Show Magazine some years ago; I have never actually touched one myself.

A man bag....a satchel.....just please no fanny packs!

My backhoe attachment is self-contained, driven off PTO pump, so I don't have the disconnect problem there, but the FEL on my uncle's tractor DID, and HE had to fight with it same way (sat in the sun, and as Dave said... don't ask how I know...)

Shutting down the engine on the tractor, then wiggling the valves to equalize relieved the tractor side.  Wiggling the valves on the loader side (valves are on the loader side) cleared the bottled pressure on the loader side.

In the beginning, God gave us Plumbing, and contrary to what you MAY HAVE BEEN TOLD, PLUMBING was the ROOT OF ALL EVIL.  Pipes were always in the way, subject to damage, and constantly leaking.  Quick disconnects were a really great invention to add to implements... a great idea, but on the other hand, a bad idea... as they allowed great places for fluid to leak out, and even worse, dirt to get in.  From this came a plethora of covers, caps, shields, plugs in all sorts of materials and colors... then covers, caps, shields and plugs added into the coupling to break off, fail, get stuck, snagged in hoses and PTO shields, then ripped off and lost.  Then came fancy connectors WITH shielding and seals integrated in, again, causing a further schism between mating flavors, and implement manufacturers and equipment manufacturers all picked different favorites, making previously compatible stuff now at-odds.   As companies developed different kinds of QD connectors, there became a great diaspora of incompatible mismatch, wailing, and grinding of teeth...

SO... it was another classic case of a good idea, but a bad idea.

The unfortunate reality of hydraulics, is that it doesn't take much heat for fluid to expand a little, and worse yet, if there' aeration in the fluid (air bubbles) they'll expand too, resulting in residual pressure in the lines.  Having a crossover valve to equalize CAN help, but sometimes it still doesn't... and frequently, it's too much for a clutch or a purse, and if your fanny pack is sideways on your hip, it obstructs the sidearm-sway of the swing, so a medium tote, preferably full of scented candles, rather than three bottles of wine, will work better at slamming those couplers in... but if not, the scented candles will survive still useable, the wine bottles will probably be broken, leaving a stained slurry of broken glass and swill... so bring a straw and a sock to suck it out afterwards, and don't mix your wine flavors- that's a heathen act of unthinkable barbarism that will strip you of your high-heels and little black dress for at LEAST a year.  

By the way, be very careful when sucking up the mess, because many hydraulic fluids look very much similar to Cabernet Sauvigion... but it sure-as-heck don't TASTE like it... it'll leave you with the same headache, but it WON'T make the sex any better...
