Malo sam se mailao sa ZF- ovcima, te dobio sluzbeni info da oni ne preporucuju ispiranje svojih mjenjaca, osim u slucaju kvara koji se time moze eventualno rjesiti.

Poslali su mi i sluzbeni dokument u kojem stoji:

5-, 6-, 8- and 9-speed as well as 4HP20 automatic transmissions:
ZF 5-, 6-, 8- and 9-speed as well as the ZF 4HP20 automatic transmissions are filled maintenance-free with specially developed
semi-synthetic ATF oils. However, due to the many factors influencing the service life of transmissions in individual operation, ZF
recommends an oil change after 150,000 km for its transmissions. In operating conditions with high temperatures and loads, or
with unknown vehicle use in the past, it can make sense to change the transmission oil at shorter intervals.
In each case, only released ATF oil may be used for oil changes. And oil changes must be performed in accordance with the
relevant specifications. The exception is the ZF 5HP18 automatic transmission which must be filled differently depending on the
version.
