Puch Maxi / Z-Two / Z-one

Automatic transmission fluid capacity & service interval

Puch Maxi / Z-Two / Z-one models require automatic transmission fluid with a capacity range of 170 CM3 to 280 CM3. The data covers 2 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Puch Maxi / Z-Two / Z-one automatic transmission is listed with two distinct fluid capacities under normal use conditions: 170 cm³ and 280 cm³. A difference of this magnitude between two entries for the same system typically reflects a service fill versus a full overhaul or dry fill capacity, where the smaller figure covers a partial drain-and-refill and the larger figure accounts for the total volume of an empty unit.
  • The 170 cm³ figure represents a relatively small fluid volume, consistent with the compact automatic transmission units found on lightweight mopeds of the era, where the gearbox cavity is minimal by design.
  • The 280 cm³ capacity, being roughly 65 percent greater than the 170 cm³ figure, aligns with what a complete transmission rebuild or initial factory fill would require, as residual fluid retained in passages and components is absent during assembly.
  • Both capacity entries carry a normal use condition designation, meaning neither figure is associated with a severe-duty or first-change-only service context within the listed specifications.
  • The model year span of 1980-1995 applies uniformly to both capacity entries, with no differentiation in fluid volume across that range as recorded in the specifications.
