The modulator valve is located on the LH side of the tranny and has a vacuum line going to. After replacing you have to set the modulator pressure by connecting a gauge to the tranny, removing the cover from the modulator valve and turning adjustment bar underneath. With out pictures its hard to show how the gauge is connected.

To be quite honest if you really have done the tests required to diagnose the modulator than setting the pressure should be the easy. If you have more specific questions feel free to add answers and I will do my best to help.

Sorry my answer could not be more complete.
