i have also had the same issues, on the last service i bleated all over the service manager and since that service the problem has been minimised to the point that i am satisfied with it.

very very occasionally i get a VERY slight nudge as i come to a halt and it down shifts to 1st gear, typically this will be in slow bumper to bumper traffic when instead of slowing to a stop i slow and then slightly move ahead and then stop, it seems that the tranny instead of going straight to first decides to hang onto 2nd in the chance you will be speeding up and then when the vehicle does come to a stop it goes "oh sh#t" and selects 1st.

does that make sense???

ive quized my dealer but they are vague about what they have done, claiming a software upgrade!!

i feel that overall the tranny shift quality has improved, firmed up on what it was.

i might add i also had them change the tranny fluid, i wondered if maybe they had adjusted the line pressures, as the changes as stated are marginally firmer that they were.
