Well, took it in yesterday, got it back today, they replaced the rear main seal. I asked if it could be the turbo pedastal and they thought no becuase there was no oil above the rear main seal and if it was the pedestal it would have been comming from above which it was not. Time will tell if it fixes the problem.
I also had them update the program for the engine and transmission. Haven't driven enough to tell a change in fuel economy but the shifting is definately different. It is much smoother. Anyhow, I will update Later as well.
