transmission cooler lines w140 600 coupe

[anticore]

Hello,
I have a problem which is very odd to say the least just look at the pictures:

anticore | trubka 722.362

Basically I cut (or someone else before I am not sure) through the cooling line with tranny pan screw and I need to get it fixed. I dont know how to do it the McGyver style(you can of course inspire me) so I have to ask what is the procedure of removing and installing the cooling line on the W140 600 coupe? And also what is the part number and how is it interchangable with other w140 replacement parts?

thank you
