Default transmission cooler lines

i have a 05 CTS 3.6 the radiator we got out... do i need to replace the trans lines or do those bolts come off? we tried everything the "quick release" tools pulling ect cant get them off to install the new radiator

do i need to replace the whole trans lines or is there a way to get the bolts off?

my new radiator has the 2 bolts installed

According to my 05 CTS Service Manual, "The transmission oil cooler system uses quick connect fittings throughout the system. Use a special tool to disconnect these quick connect fittings. Removing the transmission oil cooler lines without this tool will result in damage to the radiator, the transmission, and the transmission oil cooler caused by mixing the transmission oil and coolant or due to transmission oil loss.

ya the quick release is not working... it goes in a little but the "bolt or nut" will not release the line from the radiator... we unscrewed the nut from the crap radiator to try to work on it wiht it out... it really does not look like these come apart from the "bolt"
