This is one site's reference to what I'm talking about...
VSS Diagnostic Enable Minimum RPM:
Not sure exactly what this does, but I’ve been wondering if you set the rpm on this to it’s maximum value if the computer would not be able to activate the limp mode that causes the OBDI 1st-2nd shift problem. I’ve always been under the assumption that the no-shift is caused be a hard launch on sticky tires that would cause the VSS to lose it’s signal and set the trans into limp mode.
Try it and see if it works for you

Unfortunately, it sounds like your tranny is on its way out. My tranny has died twice and both times it exhibited the same symptoms as your car. Both times it was due to a burned up 3-4 clutch pack. Very rarely the tune is the problem but more often than not it's due to burned clutches. Sorry...

I would get the TC serviced. THey drain it, cut it apart, clean it, inspect it, weld it up(they may check the balance too. Not sure) The TC you can get with the Performabuilt is not that much from them. I'd just buy one of theirs rather than fussing with your stocker, waiting for it, etc.
