Additional Notes

  • The Pontiac G5 (USA / CAN) manual transaxle fluid capacity is specified as a range of 1.6 to 1.7 liters across all three engine configurations covered in the 2005-2009 model years.
  • A capacity expressed as a range rather than a fixed value typically reflects minor variation between fill conditions, such as fluid level at drain versus a fully settled static level, making the upper figure the more conservative service target.
  • The 2.2 16V (110 kW) variant spans the full 2005-2009 range, while the 2.2 16V (116 kW) variant is specific to 2009, yet both share the identical 1.6-1.7 liter transaxle capacity specification.
  • The 2.4 16V configuration, covering 2005-2009, also carries the same 1.6-1.7 liter manual transaxle capacity, indicating no displacement-driven difference in fluid volume requirements among the listed engines.
  • All three configurations are designated under normal use conditions, meaning the stated capacity applies to standard operating environments rather than severe-duty or first-fill scenarios.
  • The consistent 1.6-1.7 liter figure across the 2.2 and 2.4 liter engines suggests a shared transaxle unit is used across the G5 engine lineup for the 2005-2009 period covered in the specifications.
