Additional Notes

  • The rear differential capacity across the GMC Canyon GMT31XX platform holds 1.4–1.5 liters for all listed engine configurations, including the 2.5-liter, 2.8 TD DPF, and 3.6 V6 variants covering model years 2017-2022.
  • The front differential, present only on AWD configurations, carries a notably smaller fluid volume of 1.0–1.3 liters, reflecting the more compact housing of a front axle differential compared to a rear unit.
  • The capacity ranges given for each differential position, rather than single fixed values, account for normal variation during a service fill depending on fluid level at drain, housing tolerances, and refill method.
  • The 2.8 TD DPF is the only engine configuration with a front differential entry beginning in 2017, while all other AWD and non-AWD variants in the specifications start from 2018.
  • Two-wheel-drive configurations of the 2.5-liter and 3.6 V6 engines carry only a rear differential entry, with no front differential fluid capacity listed, consistent with the absence of a front axle differential in non-AWD drivetrains.
  • All differential fluid entries across the Canyon GMT31XX specifications are designated for normal use conditions, meaning the intervals and capacities listed apply to standard operating environments rather than severe-duty cycles such as towing, off-road use, or frequent short trips.
  • The front differential capacity range of 1.0–1.3 liters is shared identically across the 2.5 AWD, 2.8 TD DPF, and 3.6 V6 AWD configurations, indicating a common front axle differential housing regardless of engine displacement.
