All RPMs for all shift points need to be say 6600, 0 mph for manual, and adjust speed for normal and sport.

Is your car being tuned by a local guy? Is he using the beta version of HPTuners? The beta version has a lot more A6 parameters than the release version.

Yup still being tuned by Kaltech. I'll ask him about the hptuners version he has. Yeah he tuned quite a few G8's before as well as vette's with this transmission and he's never seen this berfore. We were both left just scratching our heads. By looking a bunch of different forums, looks like only a select few have this problem with tuning this tranny so I guess in a way, im not completely alone

I wonder what the conditions are for the 1 in 1000 correct shifts. I just got my HP Tuners so I'm no help right now. I hope to have a good grasp on this before too long.

I really wouldn't be able to tell you because from what I can tell, Im not doing anything any different. Sometimes it just randomly decides to work. My TCM just seems to have an attitude

I hate computers

A little late but mine seems to shift around 6 1-2 and 64-6500 2-3

Really? Wow thats interesting. Why would they set the first gear to shift sooner than the others?

To take advantage of the torque multiplacation of an auto...

FYI. The maximum shift speed for the 6L80E is 6500 RPM according so spec. I would think that is padded some what.
