The CoW TUNE! Yeah!
Hey Boss. Give me a call. Sounds like you're having issue with a bent torque tube, but I need some more
information for you. I re-read your thread, but didn't get enough from it.
Call me when you have time tomorrow and we'll see if we can get to the bottom of this.
Stay TUNED!

But is it properly filled? You had it drained at 50K miles, and now 21K miles later there is/are issues. I wouldn't rule out torque tube either since it/vibration happens under load, not in neutral.

I just spent an hour on the phone with Chuck discussing the symptoms of my current problem and possible causes. He e-mailed me several helpful links, including one to update my AutoCAL gadget we use to update my tunes. This from a guy who hasn't seen me in over two years.
If you have something positive to contribute to this discussion, I welcome it. But please do not bad mouth Chuck or his services. In my opinion, and those of hundreds of other Forum members, he's the best at what he does.

I have seen statements like this from time to time, and I honestly don't understand them. Chuck goes out of his way to explain everything his tunes do BEFORE he does them. In my opinion Chuck is a craftsman of the old school who takes great pride in his work, and he stands by everything he does. For someone to so casually say you "dumped it after a short while" is a cheap shot.

The least of the issues about the tune I got from Chuck was that it made my car feel faster, but it actually ran slower. There's not enough space here for details of my several other problems with Chuck's tune. If you PM me your phone number we can talk about it and maybe you'll understand then why I dumped it.

I already contributed to your issue when I suggested you hold it in gear with the paddles. I also asked about the fluid. Many techs don't know how to fill or check it. I personally know of 4 cases where it was overfilled and 2 that were underfilled. Not having fluid on the floor only means nothing is dripping out, but by no means is an indicator of the correct level.

My main concern here is that you have a vibration that I suspect is the torque tube
and it was mis diagnosed as a faulty harmonic balancer and the vibration is still there.
The real issue here is that I pinned your crank pulley when you were here last and I suspect that the
tech that replaced your pulley completely ignored that it was pinned and just installed the new pulley.
That's really bad considering the mods to your car. Here is what we did the last time I saw you....
Drill the crank and PIN it so the pulley does not rotate on the crank.
Install the new PIN so the pulley can not rotate on the crank.
Install the new PIN so the pulley can not rotate on the crank.
Keep me posted on this one.
I suspect that the torque tube has a bow to it and vibrates when you have the car in gear.
REMEMBER: that the flywheel, torque tube, and torque converter all spin ANY TIME THE ENGINE IS RUNNING.
You might not have a vibration in park or neutral, but when you load the torque tube and bend will get worse and cause a vibration...
Please keep in touch with me and let me know if I need to send you a crank pinning kit.
Thank you.

Final chapter
Red came home today safe & sound and vibration-free. The fix was a replacement -- and proper pinning -- of a faulty first replacement harmonic balancer.
I want to thank Schmitt Chevrolet of O'Fallon IL and our own GM Customer Svc (Kelly J) for making this right.
And I want to especially thank Chuck Mosello (Chuck/CoW) for speaking up when he did. Chuck made sure we all knew the new harmonic balancer had to be drilled and pinned to the crankshaft (like the original) to prevent total destruction of my engine.
