GMC Acadia, GMT960 (USA / CAN)

Additional Notes

• Across all GMC Acadia GMT960 AWD configurations covered by these specifications, the transfer case fluid capacity is uniformly 1 liter. A 1-liter fill is characteristic of a compact, electronically controlled transfer case unit rather than a larger mechanical part-time 4WD system.
• The 97,500-mile normal-use change interval applies to the 3.6 V6 AWD and 3.6 V6 Denali AWD from 2012-2016, as well as the 3.6 V6 Limited AWD from 2016-2017. Normal use generally refers to on-highway driving under moderate temperature and load conditions.
• Under severe use conditions, the change interval for the 3.6 V6 AWD and 3.6 V6 Denali AWD drops to 45,000 miles across the 2012-2016 model years. Severe use typically encompasses towing, frequent short trips, extreme temperatures, or off-road operation, all of which accelerate fluid degradation.
• The 45,000-mile severe interval is exactly half the 97,500-mile normal interval across every configuration where both values appear. This proportional relationship reflects a standard engineering approach to accounting for accelerated fluid breakdown under demanding operating conditions.
• The 3.6 V6 Denali AWD entry covering 2016-2017 lists only a 1-liter capacity under normal use, with no change interval recorded in the specifications. The 3.6 V6 Limited AWD covering the same 2016-2017 period, by contrast, carries both the 97,500-mile normal and 45,000-mile severe intervals.
• The Denali and non-Denali 3.6 V6 AWD variants share identical capacity and interval figures for both 2012 and 2013-2016, indicating the trim level distinction does not affect transfer case service requirements for those model years.
• The 2012 model year is listed as a standalone entry separate from the 2013-2016 range for both the standard and Denali AWD trims, even though the capacity and interval values are the same across both groups. This separation reflects a distinct specification grouping rather than a difference in service requirements.
