The non lock up valve body is different from the lockup valve body. The lockup valve body uses a boost valve to up the pressure to the converter clutch. Non lockup and lockup input shafts are different as is the reaction shaft. I'm not sure you can swap a lockup valve body and a non lockup valve body.

So your valve body has 3 wires correct? The center wire is 12 volts ignition hot. The forward wire is the O/D solenoid and the rear wire is the lockup solenoid.
