What Transmission Does the Jeep Grand Commander Use?
3 Answers
Jeep Grand Commander uses a 9-speed automatic transmission. The functions of the transmission are: 1. To change the gear ratio to meet the traction needs under different driving conditions; 2. To enable reverse driving; 3. To interrupt power transmission to the drive wheels when the engine starts, idles, the vehicle shifts gears, or needs to stop for power output. Taking the 2021 Jeep Grand Commander as an example, its body structure is a five-door, seven-seat SUV. The body dimensions are: length 4873mm, width 1892mm, height 1738mm, wheelbase 2800mm, front track 1601mm, rear track 1610mm, fuel tank capacity 70 liters, and curb weight 1995kg.
As a long-time automotive enthusiast specializing in transmission research, I have an in-depth understanding of the Jeep Grand Commander, which utilizes the German ZF 9-speed automatic transmission. This 9AT boasts an exceptional design, featuring multiple gears for intelligent adjustments—delivering instant downshifts to provide torque during off-roading, making hill climbs incredibly powerful. In urban driving, gear shifts are smooth and jerk-free, while high-speed cruising reduces engine RPM for fuel efficiency. Its core technology employs a torque converter and electronic control unit, ensuring reliability and responsiveness. Jeep chose it because it perfectly matches the 4WD system, balancing off-road adventure with everyday practicality. The only minor drawback is that early models may have had software bugs causing slight shift delays, but post-update performance stabilizes. Regular maintenance like fluid changes is crucial—recommended every 60,000 km to prevent overheating. Overall, it’s a technical standout among comparable SUVs and highly dependable.
I'm a loyal owner of the Grand Commander and have been driving it for over a year. It's equipped with a ZF 9AT automatic transmission, which provides an excellent experience. In daily city driving during traffic jams, there's no bumpiness, and gear shifts are responsive without any lag. On long highway trips, the fuel consumption is reasonable, averaging 9-10 liters per 100 kilometers. When off-roading on weekends, it automatically downshifts to deliver power in muddy terrain, making uphill climbs effortless. Maintenance is straightforward—I check the fluids every two years and haven’t encountered any issues. While not as economical as a manual transmission, it’s hassle-free and offers great value for money. If you're into versatile SUVs, this gearbox can handle all kinds of road conditions, from smooth highways to rugged mountain paths, with seamless performance. The low noise level is a major plus.
