Transmission Question





I have an 07 Z-51 A6 that for some reason l feel and hear a faint clunk when driving from first to second gears and only going under 25 mph driving around my community.
My other ride is an Audi which has the Variable tranny and is seamless.
My last two vets 96 and 02 were street tuned (auto) so the shift points were changed.
Will have my 07 street tuned when the weather breaks.
Is this normal or should have my dealer look at it? I have a bumper to bumper but do not want to cry wolf.
Thanks
Alan
