2007 auto trans problems
Has anyone with a magnasun 112 supercharger had any problems with the automatic transmissoin not up shifting correcly under WOT ? The car has less than 17,000 miles with 3:15 gears and corsa sports with no headers.
Can this be solved ? It actuall noses over and looses RPM's before it will shift to second gear.

I had the same problem with my '07 after the A&A kit installation. I took it back to my tuner and he retuned the tranny and now it shifts great. I think that all you need to do is find someone that knows how to tune the A6 for the extra power and you will be in good shape.

I had the same problem with my A6 after the Magnuson install (3 1/2 years ago). Lingenfelter raised the engine rev limiter 200 rpms and lowered the shift mph by 2-3 mph, this allowed the trans more time to complete the shift under WOT, that solved the problem. 21st Century Muscle Cars in Carollton, TX can do this for you.

If it is not a problem with your tranny and it is just the tranny tune that needs to be adjusted, I would recommend you contact RMS man here on the forum. He tuned my A6 with A&A supercharger and 3.42 gears. I had the S/C already installed when I added the 3.42 gears. The tranny tune was WAAAYY off, so I took it to him and now it runs very well. He is in Arlington, TX just north of I-20.
I'll PM you a video of my car after he tuned it.
