Product description<\/h3>\n

Vacuum modulator (VACUUM modulator) for automatic transmissions of the L3N, L4N, 4N71B and 3N71B series.

\nThe element is responsible for the regulation of the working pressure in the hydraulic system of the gearbox depending on the vacuum signal from the engine, directly influencing the characteristics and gear shifting moments.<\/p>\n

Incorrect operation of the modulator may cause gear shifts too early or too late, hard or delayed gear changes, and unstable operation of the gearbox.<\/p>\n
