Have a A6 with a T43 controler, when driving under normal conditions it seems to flare between 4th to 5th. it does it in all modes. Any hints to help rectify this problem.

I think there is a GM software update that corrects this issue. Is this a 2007 operating system and calibration?

No, it is in a 2008 vehicle OS 24243170, Cal 24243178.

Put the VIN in here:

And see if there are any updates that mention the flare fix.

Here is the CAL ID for the fix on the 2007 controllers:
24239571 - New calibration to correct 4-5 upshift flare

I don't understand what you mean by "it was correct". Put your VIN in, choose the TCM from the list of modules, and click the button to view the entire change history. That will give you a list of calibration updates and the major fix that each update contains.
