The B&M® vacuum modulator is fully adjustable and allows you to fine-tune your shift points and shift feel. This is done by turning the adjustment screw inside of the vacuum line connection for more or less diaphragm preload, thus raising or lowering part throttle shift points and line pressures. For GM TH350 and TH400 automatic transmissions.
