While I was working on replacing the Y-pipe on the exhaust I noticed that the transmission cooler lines to the radiator didn't look too hot. Since I had the Y-pipe off this was a perfect time to replace them. Bending the 5/16 diameter steel lines to the right contour took some doing. Here is the result:
Just to make sure everything fits I reinstalled the old Y-pipe to check to make sure the transmission lines weren't in the way of the exhaust.
The C-6 Transmission was leaking like a sieve around the transmission oil pan, here I find out that the some of the bolts on the pan where finger tight at best and not torqued to spec so I decided to change the transmission oil also because there was no telling if the right oil was in the transmission.
Here is a picture of the newly cleaned oil pan with gasket:

It took about 8 quarts of Dexron III to fill the transmission back up. Here is a picture with the oil pan back on:
