Engine/Transmission (1998.5 - 2002) Trans fluid leak up front?

[Devil Black Diesel]

I sprung a leak up front on the 2001 and it appears to be trans fluid all over the bottom of the oil pan and steering linkage. I cleaned it off last night and let it dry so I could identify where it's coming from and it looks like it's coming from the hose connection pictured in the the photo link below - the fluid is red in color. I'm guessing this is the hose coming from the trans cooler? Is this common? Easy to fix or a pain in the arse? How much should I expect to spend? Click link below for photo.

So I had my truck worked on today and it turns out it is the passenger side trans cooler line leaking as pictured in this photo: MobileMe Gallery



I guess there's a o-ring type seal inside where these connectors meet... the shop tried installing a couple different o-rings and could not get the leak fixed. Is this a matter of getting the correct o-ring from the dealer or will I need to replace the whole line/connectors?
