Line pressure increases because there is no slip in the torque converter. It's not a big deal, really. If you start noticing that you're leaking fluid, stop doing whatever you're doing.

Orange4boy -

I still have to find out what the voltage is... can I do this by just testing the connections to figure out the resistance, or do I really have to "watch" the voltage as it's engaged?

I'm thinking I'll probably just chance it and throw 12VDC constant to it anyway, since I can't really see the PCM sending 3.5V, 5V, 7.5V, etc... to the solenoid... it just doesn't seem likely. Maybe I'll check it out tomorrow a little more and see if I can trace the wires back to a relay or something...
