The Transmission Assembly of the GMC Acadia enables power to be transmitted to the wheels by selecting a particular gear ratio and engine torque for a particular speed. The Transmission Assembly utilizes hydraulic pressure, fluid coupling, and planetary gearsets to shift gears automatically. The concept of letting a rounded coupling slip while sending engine torque to gear train components is not new. It was already applied in the Hydra-Matic transmission. Past versions of the Acadia paired a six-speed automatic box, while newer models moved to eight and nine-speed variants. Yet every Transmission Assembly has the same aim of multiplying torque on steep climbs and cutting engine revs on highway cruises. The automatic Transmission Assembly in a GMC Acadia is all handled electronically using a transmission control module which engages the clutches around the planetary sets to perform quick, smooth changes. All of this happens without driver input. That is to say, no matching of revs is required as it is with a manual layout. Alternative designs in the industry include continuously variable units with belts and pulleys or dual-clutch systems. GMC has kept the Acadia true to the sophisticated hydraulic automatic because, in addition to durability and fuel savings, it offers easy usage for families. In every case, liquid movement inside the Transmission Assembly also cools and lubricates the moving parts, preserving long-term performance.
