Additional Notes

  • Both the 2.2 16V four-cylinder and the 3.4 V6 share an identical automatic transaxle fluid capacity of 9 liters, meaning the transmission hardware volume is consistent across engine configurations in the Pontiac Grand Am lineup covered here.
  • A 9-liter capacity for an automatic transaxle is a service fill figure, representing the working fluid volume the unit holds during normal operation rather than a total system or overhaul fill, which would typically be higher due to torque converter drainage.
  • Under severe use conditions, both the 2.2 16V and the 3.4 V6 carry a fluid change interval of 50,000 miles, while no change interval is listed for normal use conditions in either configuration.
  • The 50,000-mile severe-use interval applies to both engine variants equally, indicating no differentiation in transmission service scheduling between the four-cylinder and V6 drivetrains under demanding operating conditions.
  • The 3.4 V6 transaxle specifications span 1999-2005, while the 2.2 16V specifications begin in 2002, reflecting the later introduction of the four-cylinder variant within the generation covered by these entries.
