Help! John

[John 2003 Vette]

I have a 2006 Base Convertible with about 14000 miles on it. After I start the car in the morning I let it idle down and put it into reverse for about 30 seconds and then shift into drive. It almost snaps my neck as it really goes into drive with a bang. Had the Automatic transmission flushed by my Chevrolet Dealer about 200 miles ago and it continues to snap my neck when putting it into gear. Any suggestions

John, was it doing this before you had the trans serviced by the dealer or did it start doing this recently?

It was doing it before.
