Mine did it again today. Pulled off the M2 offramp to Beecroft, sat at the lights for about 5 mins in 1 (M mode). Accelerated when the light changed, nothing. Looked at the dash-Gear=1. Revs=2-300rpm. Lift foot, reapply- Same thing. Shift to D-Same thing. N then back to D, all fine, but engaged with a thud. Drove off. Wish I had my camera at the ready!!!
