2010 4.6 Transmission slips when I floor it on standing start

[chewpatrick]

Hi all, my genesis has 143k miles on it. I have owned it since 95K. this issue has existed for the last 3 years.
If I floor it when starting out the transmission slips. If I press the pedal about halfway down no slip, fast acceleration and no slippage in other gears.
I can accelerate hard when moving and no slip. It is interesting to me that it hasn't gotten any worse in over 40k miles. I have adapted and just push the pedal lightly when starting out and acceleration is more than acceptable. Wondering if anyone else has this issue. I can live with it as I love the car, but if it was a reasonable fix that didn't require opening the transmission I would consider it.

thanks in advance for any advice

You are driving the way you should. Keep up the good work. NEVER FLOOR IT.

BH transmissions don't handle abuse very well. Be kind to it and it should hold up fine. Thrash it and Bad_Things(TM) will probably happen.

Shifting behavior in my first '12 (now retired) improved after a dump and fill at 100kmi. YMMV

Thanks, I will continue to drive gently.
