Choosing the Right GMC Transmission: Allison 2500 vs 3000
Tyler SpanglerThe Allison 2500 and 3000 transmissions for GMC trucks differ mainly in their torque capacities and applications. The 2500 transmission, with its 2,500 lb-ft torque capacity, is ideal for everyday driving and moderate towing, offering smooth shifting, electronic controls, and fuel efficiency through its 5.09:1 gear ratio. The heavier-duty 3000 transmission, able to handle 3,000 lb-ft of torque, is tailored for more demanding tasks like towing large trailers and off-road work, featuring a 4.91:1 gear ratio and additional customization options, including a PTO feature. While the 2500 is lighter and more budget-friendly, the 3000 provides robust construction at a higher cost. For heavy towing needs, the 2023 GMC Sierra with the 3.0L Duramax engine and Denali Ultimate Trim, which comes with the Max Tow Package, offers an impressive towing capacity of up to 13,300 pounds, supported by a variety of upgrades like a trailer brake controller and enhanced suspension.
