87 CP transmission leak from radiator

[TheEnglishChap]

I need some guidance... the fitting to/from(?) the radiator for the transmission cooler(?) is leaking when running.
I have tightened it a little, but has made little difference.
I do not have the specific manual for the transmission, hence asking here.
If this fitting is at fault, will replacing it fix the leak?
What is the best way to replace it, without damaging the line?
Finally, where can I find this accursed fitting? (Do not have a p/n or anything to go along with!).
Thank you!!

probably the quick connect fittings. They go bad all the time and leak. Need the tool to pop the line out of it and new fittings to install, not really a big deal.

it uses any of the disconnect tools, mine is the plastic set that you can get at any auto parts store. These fittings should be available anywhere too, though unless you know exactly what they are called nobody is going to understand what you mean. Easier to just give them the part number.

I'd buy two of them even if you are only changing one. When the next one fails you'll have it on hand.

Thank you gadget73. I have two of those fittings added to my RA cart, including YG337 and YH380.

I actually have a spare YH380 sitting in a box since my 93 originally uses that same part. I don't need it any more since I have rotary controls installed from the later panthers around the 2000 time period. Pretty easy swap too. More of an issue on boxes, due to the requirement of finding the F150 setup complete with cable if I remember correctly. rambling aside, If you haven't ordered already and want to try my old junk, I can ship this to you if you're in the states. I'm guessing from your nickname that you're not.

Ha ha Sly, actually I am stateside, near Port Orchard, WA.
I have had this nickname since I first came over to the US in '06 - a name given by my American mates.
As for the YH380... I shall send you a message momentarily!
