A lot of your information points directly at the torque converter.

You should absolutely verify the correct tune is loaded in the ECM, as well as verifying that the timing and fuel pressure are actually correct as read by gauges and a timing light. If all of that is correct, then look at the converter.

Mike is correct about filters. The only short AC Delco filter you can trust is PF2232, the Duramax filter, which does work on the small block and big block, at least for me. Other than those, I now use Wix Racing filtrs.
