Default C7 A8 transmission problems

Having issues automatic transmission which while occassionally happen are occuring more frequently........

When stoping Vette lunges forward one to several times
Other times there is a thunk
When first start I live on a hill . When transmission automatically shifts from first to second it dogs ( hesitates ,slows down then shifts).

Have appointment with dealer Monday. Curious if this may be part of the transmission problems that have occurred.
Thank you

I actually have zero symptoms...my car has 11k miles on it but the P/T warranty will be up in May so I decided to do it.
