I called the service department at the dealer that worked on my
throttle lag issue.  It was simpler than I remembered.  They reset the
memory in the transmission by pulling the fuse for a period of time.
They used a tool to analyze the computer but didn't find anything that
needed to be adjusted.  So really all they did was pull the fuse and
put it back in.  I imagine you would want to leave the fuse out for
several minutes.  The car still responds when you tell it to go.  I
didn't think they would have any impact on it but it really worked.
