Maybe I'm confused. I thought you had the tcm/tcu disconnected and were shifting manually with the shifter? If that's that case, then there is nothing commanding the torque converter to lockup. Or do you have the tcm/tcu plugged in and it's correctly shifting on its own? (which would say you don't have a tranny versus computer mismatch)
