The slip value we would set to about 300 and it would instantly lock up when commanding 3rd gear, if we set it higher to something like 6000 it would slip a lot more and actually gain slip over a non-locked converter. As a work around we'd command 3rd to come on immediately and use the delay to keep it from coming on too early. It seems when the PCM commands 3rd no matter if its made the shift from 2nd already or not it will start locking right away.
I'd like to get a better description of how this works myself, it doesn't seem to match the descriptions with logic.
