Ferrari 400

Automatic transmission fluid capacity & service interval

Ferrari 400 automatic transmission fluid capacity is 12 liters. Service intervals are 20000 km and 30000 km. The data covers 4 configurations.

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

Type	Specifications
400 GTi (1979-1985)	Use: Normal Capacity 12 liter Change 30000 km Code: 3/1
400 GTi (1979-1985)	Use: Severe Capacity 12 liter Change 20000 km Code: 3/1
400 GT (1976-1979)	Use: Normal Capacity 12 liter Change 30000 km Code: 3/1
400 GT (1976-1979)	Use: Severe Capacity 12 liter Change 20000 km Code: 3/1

The Ferrari 400's automatic transmission holds 12 liters of fluid across all listed configurations, a notably large fill volume reflecting the size and complexity of the gearbox fitted to a grand touring car of this class.
The 12-liter capacity figure applies equally to the 400 GT (1976-1979) and the 400 GTi (1979-1985), meaning no difference in transmission fluid volume exists between the two variants.
Under normal use conditions, the change interval for the 400 GT automatic transmission fluid is set at 30,000 km.
Under severe use conditions, the 400 GT (1976-1979) automatic transmission fluid change interval shortens to 20,000 km, a reduction of 10,000 km compared to the normal use schedule.
The 400 GTi (1979-1985) carries the same interval structure as the earlier 400 GT, with a 30,000 km change interval under normal use and a 20,000 km interval under severe use conditions.
The alignment of fluid capacity and service intervals across both the 400 GT and 400 GTi suggests the two variants share the same automatic transmission unit for fluid servicing purposes.
