Just got back from the dealer after a supposed transmission flash. Under the hood the tech had written down TSB 18-07-99. The only problem is that I can't find that particular TSB on any lists. Anybody every hear of this one? BTW, it was taken in for an ongoing rear end vibration that they cannot seem to fix (or want to fix). Why they wanted to flash the transmission I have no idea, but what the heck. I now have invoice number 5 for the same problem. Just adding to my arsenal...
