We might have it licked (cross your fingers).
This time they got the fault "Open circuit / ground short not present" on the tiptronic.
Problem is that nothing was found to cause such a thing. All the wiring and grounds still check out.
So in the end we put in a second ground wire from the torque tube to the body, thereby hopefully circumventing the gremlin, wherever he may be.
Now my dash voltage is pretty consistently between 12 and 12.5 (I am 1 low on the dash).
No problems with the tiptronic, and overall power fluctuations seem to be a lot less (would drop .5 before when stepping on the brakes).
She has been running so good in fact, I decided to correct my stereo weirdness by getting a new deck today.
Thanks to everyone to replied to my previous posts on my electrical issues - I really hope I NEVER bring them up again!
