Why would Convertible Automatic 2015 Corvette C7 Z06 need no transmission coolers to complete Nurburgring run?

Because it would be raining as with C7 Stingray in 2013 and "unfortunately" +Tadge Juechter would not be able to conduct a "meaningful run" anyway, wink wink.

Here is an idea for Tadge, why not set up a Coffee and Cars 30 mph course instead?  Maybe throw in a waxing competition as well?  The convertible Z06 should be great for waxing, no time lost for the non existent quarter panel ducts, LMAO.
