Ok, my girlfriend bought an S4 about 3 weeks ago. Previous owner put over $7k into a "Level 10" transmission upgrade. We noticed within a week that the transmission was acting up. Now when going from a dead stop the transmission is not engaging. I noticed that the gear indicator is reversed in color (black on red vs. red on black) *see below. When going trough the shifter I can feel it engaging, but still won't go. I've had it pop into gear w/ a violent lurch. If I put it in park and remove the key and reinsert the gear indicator returns to normal, still not in gear. Eventually after working through the shift **** positions it will go into gear. Obviously threw a CEL as seen in the pic. I will scan tonight and post the codes. I'm a noob to the Tiptronic. I've done some searching, but having difficulty finding the same situation.

I believe that this is all the correct info:
KW1281
5HP19-FLA



It seems as though the car is only going into 4th (limp mode). It will not go into 1st 2nd or reverse.
Here is an update w/ some additional information:

I went ahead and ordered all the goodies to the do an ATF drain/flush/fill along w/ a new filter and seals.

Here are the codes I pulled w/ the VAG-COM:
