Ehh, no go guys. I called the AAMCO shop here in town and they said it is actually a pretty common practice to drag up a vehicle on the flatbed whenever they cannot get it out of PARK. They said that it is very unlikely for it to affect anything and doesn't hurt gearing or anything else. They added that the only mechanism that could be affected, if any, is the Park mechanism within the transmission... so they said that if that doesn't work in any way (i.e. stuck in PARK, can't get into PARK, etc) then I might have something but other than that it is probably coincidental.
Now, as far as my symptoms, their rep stated that it could be just that I need to service my front axle. He said that in all wheel drive vehicles, there are "clutch disks" within the axle that compensate for wheel travel in turns as the total distance traveled by each of the front wheels is different (i.e. inside wheel travels less distance than the outside wheel in turns) and when you get low on gear oil, if it is broken down and is no longer able to properly lubricated axle components then you would get what he called "shudder" effect.
So boys and girls, I'm off to change that oil.... !
