Saturn Relay (USA / CAN)

Automatic transmission fluid capacity & service interval

Saturn Relay (USA / CAN) uses automatic transmission fluid with a capacity range of 7 to 8,3 liters. Service intervals include checks every 12 months and changes at 80000 km, 83000 km, 160000 km, and 166000 km. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Saturn Relay (USA / CAN) automatic transaxle fluid capacity holds at 7 liters across both the 3.5 V6 (2004-2006) and the 3.9 V6 (2006-2008), indicating a consistent transaxle unit size between those two engine configurations.
  • The 3.9 V6 AWD configuration (2006-2007) carries a notably higher transaxle fluid capacity of 8.3 liters compared to the 7-liter figure for the front-wheel-drive variants, reflecting the additional fluid volume associated with an all-wheel-drive transaxle assembly.
  • Under normal use conditions, the 3.5 V6 specifies a fluid change interval of 166,000 km, while under severe use conditions the same engine configuration calls for a change at 83,000 km, exactly half the normal interval.
  • The 3.9 V6 (2006-2008) in normal use carries a change interval of 160,000 km, which is 6,000 km shorter than the 166,000 km interval specified for the earlier 3.5 V6 under the same use condition.
  • Under severe use conditions, the 3.9 V6 and the 3.9 V6 AWD both share an 80,000 km change interval, while the 3.5 V6 under severe use specifies 83,000 km, a slight difference between the engine generations.
  • The 3.5 V6 specifications include a fluid check interval of 12 months for both normal and severe use conditions, a detail absent from the 3.9 V6 and 3.9 V6 AWD rows.
  • The 3.9 V6 AWD under normal use shares the same 160,000 km change interval as the standard 3.9 V6, meaning the addition of all-wheel drive does not alter the recommended change frequency despite the larger fluid capacity.
