Additional Notes

  • The Chevrolet Uplander (USA / CAN) carries a 7-liter automatic transaxle fluid capacity across all model years from 2005-2008, applying equally to both the 2005 and 2006-2008 3.5 V6 configurations. A 7-liter figure for an automatic transaxle represents a service fill volume, meaning the amount used during a fluid change rather than a full overhaul refill, which would typically be higher.
  • Under normal use conditions, the 3.5 V6 transaxle carries a fluid change interval of 100,000 miles for both the 2005 and 2006-2008 model year groups, paired with a 12-month check interval regardless of mileage accumulation.
  • Under severe use conditions, the change interval for the automatic transaxle drops to 50,000 miles across all 2005-2008 model years, representing a 50 percent reduction compared to the normal use interval, while the 12-month fluid check schedule remains unchanged.
  • The split between a 100,000-mile normal interval and a 50,000-mile severe interval reflects how operating conditions directly affect fluid degradation rates in automatic transaxles, with severe duty cycles generating more heat and mechanical stress that accelerate fluid breakdown.
