Transmission cooler lines install

[Big T]

Looking at Path of the transmission cooler lines after installing the engine and it looks difficult to near impossible to thread the hard lines through without removing the passenger side exhaust manifold. Can someone confirm that is the case or if not, suggest an alternative approach?

I just did that. OEM lines.
From the front with rad support removed,
and rad hoses out of the way.
It is a 2wd 6.5 burb.
It did require some manipulation.

This is a 4wd K2500 Suburban. Just looks like a tough fit between engine mount and exhaust manifold. Maybe I was just tired?
