• They are responsible for the tightness of the clutch and braking packages and, as a result, for the long life of the clutches and bushings. The rubber of the rings deteriorates or "stiffens" from time and temperature, which leads to a loss of pressure in the line. There is also mechanical damage to the ring, caused either by errors during installation or by large crumbs of metal (or plastic) from destroyed bearings, gears, washers.

The average guaranteed service life of rubber rings in automatic transmissions ranges from 4 years to 7 years at moderate operating temperatures. According to the standards of automatic transmission service - if the machine has worked for more than 7-10 years and the mileage has exceeded 150000. km, then all rubber rings should be replaced during overhaul. .
