Additional Notes

  • The Pontiac G6 (USA / CAN) automatic transaxle fluid capacity varies by engine, ranging from 6.6 liters on the 3.5 V6 to 9 liters on both the 3.6 V6 24V and 3.9 V6 configurations.
  • The 2.4-liter automatic transaxle carries a capacity listed as a range of 6.6 to 7 liters, which reflects a tolerance window rather than a fixed fill value, distinguishing it from the single fixed figures assigned to the V6 engines.
  • The 3.5 GT, covering model years 2005-2006, shares the same 7-liter transaxle capacity across both normal and severe use conditions, making the fill volume consistent regardless of operating environment.
  • The 3.6 V6 24V and 3.9 V6 engines, both spanning 2006-2009, share an identical 9-liter automatic transaxle capacity, the highest figure across all G6 engine variants in the specifications.
  • The 3.5 V6 for 2006-2009 carries a fixed 6.6-liter transaxle capacity, which is the lowest single-value figure among the V6 configurations listed.
  • A 50,000-mile fluid change interval applies under severe use conditions across all engine variants in the specifications, including the 2.4, 3.5 GT, 3.5 V6, 3.6 V6 24V, and 3.9 V6.
  • No fluid change interval is listed under normal use conditions for any of the G6 automatic transaxle configurations, meaning the 50,000-mile interval is exclusively tied to severe use service in the specifications.
  • The 3.5 GT designation covers only 2005-2006, while the remaining four engine variants, the 2.4, 3.5 V6, 3.6 V6 24V, and 3.9 V6, all share the 2006-2009 model year range for automatic transaxle service data.
