Additional Notes

  • The Chevrolet Trailblazer VSS-F automatic transmission is configured as a transaxle, meaning the transmission and drive axle share a single integrated housing rather than being separate assemblies.
  • Across all listed AWD configurations, the overhaul capacity falls within a range of 8.5-9.5 liters, reflecting the total fluid volume required when the transaxle is fully disassembled and refilled from dry.
  • The service fill capacity of 5-6 liters is notably lower than the overhaul figure, as a routine fluid change does not evacuate fluid retained in the torque converter and internal passages.
  • The gap between the 5-6 liter service fill and the 8.5-9.5 liter overhaul capacity indicates that roughly 3-4 liters of fluid remains in the transaxle during a standard drain-and-fill service.
  • All listed configurations carry a 45,000-mile change interval applied under severe use conditions, which typically refers to operating environments involving frequent towing, extreme temperatures, stop-and-go traffic, or similar high-stress driving patterns.
  • Both the 1.2 Turbo AWD and 1.3 Turbo AWD variants share identical capacity figures and service intervals across the 2020-2022 model years, indicating no differentiation in transmission fluid specifications between the two engine displacements in AWD trim.
