That's what I think too. But....
The lockup valve will still move to open sending pressure towards the converter.
The solenoid (normally open) allows the pressure to vent, then when the solenoid is closed it allows the converter to pressurize, locking it.
At least that's how I, as not a transmission expert, think it works.
Would it be better to block the lockup valve closed so all that pressurised fluid isnt whirring around unnecessarily?
