tiptronic connection, no4 solonoid

[killalux]

Hey, i have a tiptronic auto controller from AWshifting, I am connecting it to a ls400 / celsior A341E trans.
My question is the trans has a 4th solonoid (no.4) for modulator pressure control during shifts. Do i need to supply a signal to this, or if it is left unpowered will it just hold full accumulator pressure during shifts.

I have searched but have not found any mention of the no 4 solonoid.

thanks
steve
