The GMC Canyon I Crew Cab, produced from 2007 to 2012, represented GMC’s entry into the mid-size pickup truck market in North America. Positioned below the full-size Sierra, the Canyon aimed to provide a more manageable and fuel-efficient option for buyers who didn’t require the larger truck’s capabilities. The 2.9-liter inline-four engine paired with a four-speed automatic transmission was a key configuration during this generation, serving as the base powertrain for the Crew Cab model. It offered a balance between affordability and capability, targeting buyers seeking a versatile truck for both work and personal use. This variant was part of the first generation Canyon (model code: GMT900), sharing a platform with the Chevrolet Colorado.

Powertrain & Engine Architecture
The 2.9-liter LLV inline-four engine was a key component of the Canyon’s base powertrain. This engine, a descendant of earlier GM four-cylinder designs, featured a cast iron block and an aluminum cylinder head. It utilized multi-port fuel injection for precise fuel delivery and a double overhead camshaft (DOHC) valvetrain with variable valve timing (CVVT) to optimize performance and efficiency across the rev range. The engine produced 185 horsepower at 5600 rpm and 190 lb-ft of torque at 2800 rpm. The Hydra-Matic 4L60-E four-speed automatic transmission was the sole transmission option for this engine. This transmission was known for its durability but was considered somewhat dated by the end of the Canyon’s production run, lacking the efficiency of newer five- or six-speed automatics.
Driving Characteristics
The 2.9-liter engine and four-speed automatic combination in the Canyon Crew Cab delivered adequate, but not exhilarating, performance. Acceleration was modest, and the truck felt noticeably slower when fully loaded or climbing hills. The four-speed automatic’s gear ratios were spaced relatively wide, resulting in a noticeable drop in engine speed during shifts. Compared to the optional 3.7-liter inline-five or the more powerful 5.3-liter V8, the 2.9-liter felt underpowered, particularly for towing. However, the lower engine weight contributed to better handling and a more comfortable ride. The automatic transmission prioritized smooth operation over aggressive shifting, making it suitable for everyday driving and light-duty tasks.
Equipment & Trim Levels
The 2.9-liter engine was typically found in the base and mid-level trim packages of the Canyon Crew Cab. Standard features generally included air conditioning, power windows and locks, and a basic audio system. Higher trim levels added features such as alloy wheels, upgraded interior materials, a premium sound system, and a power driver’s seat. Optional extras included a towing package, off-road suspension, and a navigation system. Interior upholstery was typically cloth, with leather options available on higher trims. The dashboard layout was functional and straightforward, prioritizing usability over luxury.
Chassis & Braking
The Canyon I Crew Cab utilized a body-on-frame construction, providing a robust and durable platform. The front suspension consisted of independent coil springs, while the rear suspension employed leaf springs. This configuration was typical for mid-size trucks of the era, balancing ride comfort with load-carrying capacity. Braking duties were handled by ventilated discs at the front and drum brakes at the rear. An anti-lock braking system (ABS) was standard. The steering system was a hydraulic rack-and-pinion setup, providing responsive and predictable handling. The 2.9L models generally had a slightly softer suspension tune compared to the V8 models, reflecting their lower weight and intended use.
Market Reception & Comparison
Critics generally viewed the 2.9-liter Canyon as a competent but unremarkable performer. While the engine offered acceptable fuel economy – around 18 mpg city and 24 mpg highway – it lacked the power and refinement of its competitors’ offerings, particularly the Toyota Tacoma and Nissan Frontier. The four-speed automatic transmission was also criticized for being outdated. However, the Canyon’s affordability and spacious Crew Cab configuration were seen as strengths. Compared to the higher-trim Canyon models with the larger engines, the 2.9-liter version offered a lower price point but sacrificed performance and towing capacity. Reliability was generally good, with the 2.9-liter engine proving to be relatively durable.
Legacy
The 2.9-liter engine and four-speed automatic transmission combination in the GMC Canyon I Crew Cab represents a solid, if unspectacular, powertrain. While not known for its performance, it offered a reliable and affordable option for buyers seeking a mid-size pickup truck. Today, these trucks are relatively common on the used car market and can be found in good condition with reasonable mileage. The powertrain is generally considered to be durable, but regular maintenance is essential to prevent issues. The 2.9L Canyon is often favored by those seeking a simple, dependable truck for light-duty tasks, rather than a high-performance or heavy-duty workhorse.
