Additional Notes

  • The GMC Canyon GMT31XX-2 transfer case holds 1.5 liters of fluid across all listed AWD configurations, a figure consistent with a service fill rather than a full overhaul capacity.
  • Under normal use conditions, the transfer case fluid change interval is set at 100,000 miles for both the 2.7 Turbo AWD and the 2.7 Turbo High Output AWD.
  • Under severe use conditions, the change interval drops to 50,000 miles, which is half the normal-use interval, applying equally to both the 2.7 Turbo AWD and the 2.7 Turbo High Output AWD.
  • The 1.5-liter transfer case capacity is identical between the standard 2.7 Turbo AWD and the 2.7 Turbo High Output AWD, indicating no difference in transfer case hardware between the two output variants.
  • The severe-use interval of 50,000 miles reflects the increased mechanical stress and fluid degradation associated with demanding operating conditions, such as frequent towing, off-road use, or extreme temperatures.
