I have a 2004 Auto steptronic with GM transmission. Yesterday, I was out playing with dynolicious on my ipod, and the reverse gear slipped a couple times while backing out of a driveway. After gassing it a couple of times to reproduce the problem, it started working fine. Later on the way home, my gear indicator on the dash stopped reading "D" and was reading blank in drive. If I shifted into S/M, or manually, it read correctly, but was blank in drive. Then later still, it started reading "N" while in drive, and now the shift interlock solenoid clicks upon brake pedal application.

WTF man. I just spent $2500+ repairing and replacing stuff on this heap.
