Hey Red, not to question your vast amounts of knowledge, but how did you know? I had heard that anything with a 4l60E later than 1996(?) or so has to be a lock-up. Is that true?

The 4L60Es have a torque convertor clutch (internal to the convertor) which defines lockup vs. non-lockup. If you want non-lockup, just cut the wire that supplies ground or power to the TCC circuit.
Also, as far as I know, all GM transmissions with a lockup convertor will have an o-ring groove on the input shaft.
