A8 cold 1-2 shift problem solved?
There are A8 owners, including me, who still have harsh 1-2 shifts after re-flashing and the "learning" procedure.
There is a thread on another C7 forum about this problem. The OP's dealer found that the trans fluid was 1.5 quarts low. Adding fluid solved the problem.
It makes sense that this might cause the problem. Once the transmission heats up the fluid expands, increasing the level. Since it is not easy to check the level (no dip stick), dealers don't normally check it during routine maintenance.
Has anyone else had experience with this solution?

My Vette shifts are not what I would call "harsh" but there is a noticeable "pause" in the first two shifts from 1st to 2nd when the car has been in the garage all night and the temps are high 30's. It just turned 1000 miles and I am counting on the shifts getting smoother.

You can't. It's basically a HUGE PITA to try it on your own and the dealership has to check it for you. So, if at any time your Vette is in the shop make it a standard MO that your tranny fluid is checked since you can't do it yourself. Why the engineers designed it this way is beyond me.

I had great success with Service Bulletin 14-07-30-001A.
Very simple to do.
Keep transmission in Manual Mode.
Keep transmission in 7th gear.
Set cruise control at 52mph.
Cruise for 10 miles.
I did this twice on a recent trip, with 40 miles of normal "D" driving
in between, and it eliminated the 1st to 2nd lag entirely.
My car can set for two weeks without driving, so it is really cold at start up.
Let me know if anyone try's this and if it worked for you,
Thanks
