Additional Notes
- Both the 2.5L four-cylinder and the 2.8L V6 configurations of the Pontiac Fiero share an identical manual transaxle fluid capacity of 2.5 liters across the full 1984-1988 model year span.
- The 2.5-liter capacity figure represents a service fill level, meaning the amount of fluid required during a routine drain and refill rather than a complete overhaul or rebuild procedure.
- Both engine variants use a transaxle layout, which combines the transmission and final drive axle into a single unit. A shared fluid capacity between the two despite differing engine displacements points to a common transaxle housing used across the lineup.
- All listed specifications carry a normal use condition, meaning the stated 2.5-liter capacity and associated service parameters apply under standard driving circumstances rather than severe or high-stress operating conditions.
