There is a small leak from the back transmission coolant line. How can this problem get resolved without the engine having to be removed?

Upper tranny cooler line pulled out of quick connect at transmission. Lost all fluid within a minute. Good thing it happened in my driveway and not on a highway ir a $25 parts could have caused a $3500 trans replacement. Been a cadi guy all my life and the 2008 DTS has been a money pit...

Transmission line connector broke. I lost all fluid. Fluid all over my brakes.
The rear coolant line going into the transmission leaks, . Not sure how to fix it? Can't get a wrench on the damn thing. Trying to check out this web site to see if the solution is to pull the Engine Cradle and work from there?
