3 Answers
The transmission of the Buick GL8 is a 6-speed DSS intelligent transmission, model 6T45E, paired with a 2.0T SIDI direct-injection turbocharged engine for power output. It has a low failure rate and offers stable and reliable performance. The 6AT transmission in the Buick GL8 Landmark 3.0L shifts very smoothly. Although it has fewer gears, excellent calibration controls the larger shift transition gaps. The Buick GL8 is a classic top-tier MPV under the Buick brand. The Buick GL8 family consists of the GL8 Avenir, GL8 ES, and GL8 Business Travel models, forming a three-pronged product lineup. The entire series is equipped with a 2.0T SIDI direct-injection turbocharged engine, delivering a maximum horsepower of 191 and a top speed of 205 km/h, all meeting the China VI emission standards.
I've been driving the Buick GL8 for over a decade. It features a 9-speed automatic transmission with smooth gear shifts and no jerking, making the ride exceptionally stable. In earlier years, the older models with 4AT had higher fuel consumption and were prone to gear sticking. Now with the 9AT, it's noticeably more fuel-efficient, consuming only about 7-8L on the highway, with quick acceleration response, giving confidence when overtaking. Maintenance-wise, it's important to change the transmission fluid regularly, typically every 40,000 kilometers, otherwise, the clutch plates may wear out and cause unusual noises. Buick equipped this transmission for comfort and fuel efficiency, combined with its spacious interior for carrying more people, making long drives less tiring. Technically, it uses a torque converter and intelligent control system that can automatically learn driving habits, making it quite reliable and durable overall.
I bought my GL8 last year, and it comes with a 9AT transmission, making my daily commute super easy. It starts quickly without delay and remains smooth without any jerking even in city traffic jams. The fuel consumption fluctuates around 9L, which is much more economical than my neighbor's old car. On weekends, when I take my family on road trips, the transmission works quietly and powerfully with the engine, and it doesn't struggle even when climbing mountain roads. Remember to regularly check the oil level and filter—don't wait for problems to arise before fixing them. In terms of cost, an oil change and maintenance service costs around six to seven hundred yuan, which is quite reasonable. Overall, it's suitable for family use or business trips, with good reliability and no major issues.
