Nissan 300 ZX (EU)

Automatic transmission fluid capacity & service interval

Nissan 300 ZX (EU) automatic transmission fluid capacity ranges from 7 to 8,7 liters. Service intervals require checks every 20000 km or 12 months. The data covers 3 configurations.

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

Additional Notes

  • The Nissan 300 ZX (EU) automatic transmission fluid specifications cover two distinct chassis generations: the Z31, spanning 1984-1990, and the Z32, introduced in 1990.
  • The Z31-based 300 ZX Turbo (1984-1990) and the naturally aspirated Z31 300 ZX (1984-1989) share an identical automatic transmission fluid capacity of 7 liters, indicating a common transmission unit across both variants of the Z31 platform.
  • A 7-liter capacity is consistent with a full system fill, accounting for fluid held within the torque converter, valve body, and transmission pan rather than a partial drain-and-fill service quantity.
  • The Z32-generation 300 ZX Twin Turbo (1990-1991) carries a notably higher automatic transmission fluid capacity of 8.7 liters, reflecting the physically larger transmission unit fitted to the twin-turbocharged Z32 platform compared to the Z31.
  • The 1.7-liter difference in capacity between the Z31 and Z32 transmissions is a meaningful distinction for service purposes, as underfilling an 8.7-liter system with a Z31-based 7-liter quantity would leave the transmission significantly low on fluid.
  • Among the three configurations listed, only the Z32 Twin Turbo carries an explicit service interval: a fluid check at 20,000 km or 12 months, whichever occurs first, under normal use conditions.
  • The 20,000 km or 12-month check interval specified for the Z32 Twin Turbo represents a condition-monitoring interval rather than a full fluid replacement schedule, as the specification references a check rather than a change.
