Additional Notes

  • The Chevrolet Colorado GMT31XX-2 (USA / CAN) transfer case holds 1.5 liters of fluid across all listed AWD configurations, a figure that reflects a service fill volume rather than a full overhaul or dry-fill quantity.
  • Both the 2.7 Turbo AWD and the 2.7 Turbo High Output AWD share an identical 1.5-liter transfer case capacity, meaning no difference in fluid volume exists between the standard and high output engine variants.
  • 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 configurations starting from 2022.
  • Under severe use conditions, the same configurations carry a transfer case fluid change interval of 50,000 miles, exactly half the normal-use interval, reflecting the additional stress placed on the fluid under demanding operating circumstances.
  • The halving of the change interval from 100,000 miles under normal conditions to 50,000 miles under severe conditions applies equally to both the 2.7 Turbo AWD and the 2.7 Turbo High Output AWD, with no deviation in interval structure between the two engine variants.
