Re: M40 adjustments
I believe the TH400 uses a vacuum modulator to vary line pressure based on engine vacuum. There are adjustable modulators available that allow the driver to vary the line pressure with the turn of a wrench. The modulator is mounted on the passenger side of the tranny and has a steel line going to the intake manifold vacuum fitting.
