Vauxhall Firenza
Automatic transmission fluid capacity & service interval
Vauxhall Firenza uses automatic transmission fluid with a capacity of 2,6 liters. Service intervals include checks every 10000 km or 3 months and changes every 24 months or 40000 hours. The data covers 3 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.
| Type | Specifications |
|---|---|
| Firenza 1.3 (1972-1975) |

Additional Notes
- The Vauxhall Firenza automatic transmission service fill capacity is 2.6 liters across the 1.3, 1.8, and 2.3 engine variants for the 1972-1975 model years. A service fill figure represents the amount of fluid added during a routine drain-and-fill procedure, not the total system volume, which would be higher in a full overhaul scenario.
- All three engine configurations share an identical 2.6-liter service fill capacity, indicating no variation in automatic transmission fluid volume requirements between the 1.3, 1.8, and 2.3 displacements within the 1972-1975 range.
- The fluid check interval is specified at 10,000 km or 3 months, whichever comes first. A distance-and-time dual threshold of this kind means the time limit applies even when mileage accumulation is low, such as in vehicles used infrequently.
- The fluid change interval is set at 24 months or 40,000 hours. An hour-based threshold of 40,000 hours is an unusually large figure in the context of typical vehicle operation, where an engine running continuously would take many years to reach that count, making the 24-month calendar interval the practically governing condition in most use cases.
- All specifications across the 1.3, 1.8, and 2.3 variants are designated under normal use conditions, meaning the check and change intervals listed apply to standard operating environments rather than severe-duty cycles.
