Additional Notes

  • The Buick LaCrosse 3.6L V6 VVT AWD transfer case holds 0.65 liter of fluid, a figure consistent with the compact, electronically controlled transfer cases found in front-wheel-drive-based AWD platforms, where the unit is relatively small compared to those in body-on-frame or dedicated four-wheel-drive vehicles.
  • The 0.65-liter capacity applies to normal use conditions, meaning the interval and fill quantity are calibrated for standard driving cycles rather than the more demanding thermal and mechanical stress associated with severe use classifications.
  • A transfer case capacity at this volume typically reflects a service fill rather than a full overhaul quantity, as overhaul procedures on units of similar design often account for additional fluid retained in internal passages and the torque coupling assembly that drains incompletely during a standard drain-and-fill service.
