722.3 / 722.4 / 722.5 modulators

Pressure modulator designed for 722.3 / 722.4 / 722.5 boxes. It adjusts the control pressure depending on the vacuum in the manifold and the engine load, adjusting the gear shifting torque to the driving method.

Damage is manifested by too early or too late gear changes, jerking when accelerating and the presence of oil in the vacuum line. Before assembly, compare the length of the pin, the thread of the body and the construction of the stub with the element dismantled from the box.
