Ferrari 328 GTS/GTB

Manual transmission fluid capacity & service interval

Ferrari 328 GTS/GTB manual transmission fluid capacity is 4 liters. Service intervals include checking at 10000 km and 20000 km, and changing at 2000 km and 20000 km. The data covers 2 configurations.

Additional Notes

  • The Ferrari 328 GTS/GTB carries a manual transmission fluid capacity of 4 liters, a figure that applies consistently across both the normal use and initial service conditions listed in the specifications.
  • Under normal use conditions, the check interval and the change interval are both set at 20,000 km, meaning fluid inspection and replacement fall on the same service event rather than being staggered.
  • The initial service condition specifies a change interval of just 2,000 km, which is a significantly shorter interval than the 20,000 km change interval assigned to normal use. Early fluid changes at low mileage are associated with flushing out metal particles and manufacturing residues that accumulate during a gearbox's break-in period.
  • Although the fluid capacity remains at 4 liters under the initial service condition, the check interval for that condition is listed at 10,000 km, half the 20,000 km check interval used for normal operation.
  • The 4-liter capacity figure is consistent with a full-fill specification rather than a partial top-up volume, as it represents the total fluid volume the transmission holds when properly serviced.
