Additional Notes

  • The Chevrolet Trax VSS-F automatic transaxle carries an overhaul capacity of 8 to 8.5 liters on the 1.2 Turbo, which reflects the total fluid volume held within the unit when fully drained and refilled during a complete rebuild or replacement procedure.
  • A service fill of 4 to 6 liters applies to the 1.2 Turbo transaxle, a notably lower figure than the overhaul capacity because a routine drain does not evacuate fluid retained in the torque converter and valve body passages.
  • Under normal use conditions, no mileage-based change interval is specified for the 1.2 Turbo transaxle, whereas severe use conditions carry a defined change interval of 45,000 miles for the same unit.
  • The severe-use interval of 45,000 miles applies equally to the 1.2 Turbo FlexFuel variant introduced in 2024, with a single capacity figure of 8.5 liters listed rather than the split overhaul and service fill values seen on the standard 1.2 Turbo.
  • The 1.2 Turbo FlexFuel transaxle capacity of 8.5 liters aligns with the upper bound of the standard 1.2 Turbo overhaul range, suggesting the listed value for the FlexFuel configuration represents a full-system capacity rather than a partial service fill.
