What Transmission Does the Grand Commander Use?

[Joel]

The Grand Commander is equipped with a 9AT transmission, which offers smooth shifting and excellent reliability and durability. The Grand Commander is a midsize SUV under the Jeep brand, featuring two engine options: a low-power version of the 2.0-liter turbocharged engine and a high-power version of the 2.0-liter turbocharged engine. Below are the details about the Grand Commander: 1. The low-power 2.0-liter turbocharged engine delivers 234 horsepower and a maximum torque of 350 Nm. This engine reaches its peak power at 5,000 rpm and its maximum torque between 2,500 and 4,500 rpm. It features direct fuel injection technology and an aluminum alloy cylinder head and block. 2. The high-power 2.0-liter turbocharged engine produces 265 horsepower and a maximum torque of 400 Nm. This engine achieves its peak power at 5,200 rpm and its maximum torque between 3,000 and 4,250 rpm. It also utilizes direct fuel injection technology and an aluminum alloy cylinder head and block. 3. The Grand Commander's front suspension employs a MacPherson independent suspension, while the rear suspension uses a multi-link independent suspension. 4. The Grand Commander is available in both front-wheel-drive and four-wheel-drive versions. The four-wheel-drive models are equipped with an on-demand four-wheel-drive system and a multi-plate clutch-type central differential.

I recently researched the Jeep Grand Commander, and its transmission is worth discussing in detail. The vehicle is equipped with a 9-speed automatic transmission, model number 948TE. This transmission has a notable feature: it shifts very smoothly, especially during high-speed cruising where it's particularly fuel-efficient. A friend of mine drove the Grand Commander from Shanghai to Hangzhou at a constant speed of 120 km/h, with the engine RPM staying around 1800, making the engine noise almost inaudible. This transmission pairs exceptionally well with the 2.0T engine, with almost imperceptible shift actions during acceleration. As for drawbacks, there might be occasional slight jerks at low speeds, but recent software updates on newer models have significantly improved this. Jeep specifically chose this 9AT to enhance fuel economy, resulting in nearly a 15% reduction in fuel consumption compared to the older 6AT. It's recommended to change the transmission fluid every 60,000 kilometers to avoid affecting shift responsiveness. Overall, this transmission balances comfort and economy, making it particularly family-friendly.

As an experienced driver, I've driven quite a few Jeep models. The Grand Commander uses an improved version of the same ZF 9-speed transmission found in its sibling, the Grand Cherokee. This 9AT is particularly smart in city traffic jams. Driving it feels like having a seasoned dispatcher who always selects the right gear based on throttle input. For example, it quickly downshifts to maintain power when climbing hills, and immediately upshifts for fuel efficiency on flat roads. However, its most impressive feature is its towing capability—I've seen people tow yachts with the Grand Commander, with the transmission temperature remaining perfectly stable. Remember to regularly check the transmission fluid level; last time, my neighbor's car had delayed gear shifts due to a leaking oil seal. Modern automatic transmissions are much more worry-free than the manual transmissions we drove in our younger days, especially with gear ratio designs like this 9AT that make the Grand Commander's power delivery exceptionally smooth.

The Grand Commander's transmission system is quite interesting. The currently available models are basically equipped with a 9-speed automatic transmission, paired with a 2.0T engine. During my actual test drive, I noticed a detail: there is absolutely no delay when shifting into reverse gear. This transmission automatically adjusts its shifting strategy in off-road mode, such as holding lower gears to provide engine braking during steep descent. Some owners have reported slight jerks during cold starts, but it becomes smooth after the engine warms up. Compared to CVT transmissions, this 9AT is more robust and durable, making it particularly suitable for those who enjoy road trips. However, it's important to use certified transmission fluid during maintenance, as there was a case where a workshop used the wrong oil, leading to solenoid valve failure. Jeep's choice of the 9AT for this model is indeed appropriate, ensuring both highway comfort and meeting off-road demands.

As a Jeep owner, I really can't find any major flaws with the Grand Commander's 9-speed automatic transmission. It's smooth for daily school runs with the kids and powerful enough for weekend mountain drives. When I borrowed a friend's Grand Commander for a long trip, the most noticeable feature was the quick response of the steering wheel paddle shifters for downshifting - overtaking was crisp and decisive. This transmission is quite different from the Wrangler's setup, placing more emphasis on comfort with much gentler gear shifts. What's particularly impressive is its intelligent torque converter, which reduces power loss at low speeds through partial clutch engagement. However, it's best to change the transmission fluid every 4 years or 60,000 km - I saw someone on the forum who waited too long and had to replace the entire valve body. Nowadays, all new cars come with start-stop functionality, and the transmission response isn't affected at all during startup - the technology has truly advanced.

Last time I accompanied my friend to check out the Grand Commander, the salesperson highlighted this 9AT transmission. It can shift into 9th gear at 120km/h highway cruising, with the RPM just over 1700, making it quiet and fuel-efficient. In actual driving, the shifting logic is very user-friendly, such as dropping 3 gears instantly for acceleration when the throttle is deeply pressed, and automatically upshifting to coast when the throttle is released. The Terrain mode switching system paired with this transmission is particularly practical, automatically starting in 2nd gear on snow to prevent slipping. For maintenance, note that the transmission filter and oil pan are integrated, so the whole set needs to be replaced when changing the fluid. But overall, its reliability is excellent, with many owners driving 80,000 kilometers without any transmission issues. Equipping the Jeep with this 9AT is a wise choice, balancing fuel economy and power performance.
