Pontiac Firebird (USA / CAN)

Automatic transmission fluid capacity & service interval

Pontiac Firebird (USA / CAN) automatic transmission fluid capacity ranges from 4,7 to 10,6 liters. Service intervals include checks at 12500 to 15000 km or 12 months and changes at 25000 to 160000 km. The data covers 6 configurations.

Additional Notes

  • The Pontiac Firebird (USA / CAN) automatic transmission service fill capacity holds at 4.7 liters across all listed engine configurations and model years, meaning a routine fluid change without a full teardown consistently requires the same volume regardless of engine size.
  • Dry fill capacity, which reflects the total fluid volume needed when filling a completely drained or rebuilt transmission, varies notably by engine. The 3.4-liter for 1992-1993 carries a 7.9-liter dry fill, while the same engine in 1994-1995 rises to 8.3 liters, pointing to a transmission change between those production periods.
  • The 5.7-liter Trans Am configuration shows two distinct dry fill values depending on model year. The 1993-1997 entry lists 10.6 liters, while the 1994-1997 entry lists 10.2 liters, indicating that two different automatic transmission units were used across those overlapping year spans.
  • Under normal use conditions, the 3.4-liter Firebird for 1992-1993 and 1994-1995 both carry a fluid change interval of 160,000 km, which is a notably long service life for automatic transmission fluid and reflects a sealed or low-maintenance design philosophy for everyday driving.
  • Severe use conditions for the 3.4-liter configurations compress the change interval dramatically, dropping from 160,000 km under normal use to 25,000 km. Severe use typically encompasses conditions such as frequent towing, stop-and-go traffic, or extreme temperature exposure, all of which accelerate fluid degradation.
  • The fluid level check interval under normal use for the 3.4-liter engine is set at 12,500 km or 12 months, whichever comes first, for both the 1992-1993 and 1994-1995 variants.
  • Under severe use, the check interval for the 3.4-liter configurations extends slightly to 15,000 km or 12 months, which is a longer distance interval than the normal-use check schedule despite the more demanding operating conditions.
  • The 5.7-liter Trans Am entries carry only normal-use specifications in the listed data, with a check interval of 12,500 km or 12 months and a change interval of 160,000 km, matching the normal-use schedule of the 3.4-liter variants.
