Thanks for your input LC. I was running in manual at the time as it doesn't recreate the issue in D. It simply just changes up a gear when the throttle is lifted slightly.
Yep, had 3 box services at 42k, 67k and 94k.
I've ran basic settings a couple of times mainly down to after my last visit to the tuner it was holding the gears a little too long in D, much like as if it was in S. It sure doesn't seem happy but i keep basically getting told it's normal
