126 270 91 79 - Automatic Gearbox Vacuum (Black Top) Modulator - 4 Speed 83 to 95

Both the Original Green & Red Top Modulators are No Longer Available. The 928 Automatic Gearbox is based on a Mercedes 722.3 & 722.4 4 Speed Gearbox common on a lot of Mercedes cars from 81 to 95. Mercedes Car Gurus found that the later "Black Top" Vacuum Modulator is an ideal replacement and works well.
