Have them give a definite reason why the exhaust would cause this problem. Dealers are notorious at blaming something on an aftermarket item, with no proof or experience when they fail to find the true problem. They may not be able to find the real problem, not due to their incompetence, but due to the fact that once in a while these new vehicles will exhibit a behavior that can't be explained.
I will check today, in case I'm wrong, but I have never in my life heard of a cat-back exhaust causing any problems with the engine or trans, and even early in the AM, I cannot conceive of what the exhaust would do to cause the problems you stated. If the exhaust was clogged, yes, but if it was clogged, it would not run ok afterward either. And what normally clogs exhaust systems, catalyst material discharged from the catalyst due to backfires. This you don't have, so I rule out the exhaust.
The exhaust is a static device, if it was causing problems, it would cause problems all the time at high altitudes, a restart would not fix the problem. (Just my opinion.)
I'm still thinking the PCM or a sensor "farted" and the restarts fixed the problem, similar to my 4-wheel drive problems on the trip. The trans bulletin is just a "maybe" since it does show some of you symptoms. Problem is you have those other codes too.
