What transmission is equipped in the Buick LaCrosse?
2 Answers
Buick LaCrosse is equipped with the Aisin 6T40E transmission from Japan. Transmissions include manual transmissions, conventional automatic transmissions, CVT continuously variable transmissions, and dual-clutch transmissions. The Buick LaCrosse uses a dual-clutch transmission. Relevant information about the Buick LaCrosse is as follows: 1. The new generation LaCrosse will switch to a 9-speed automatic transmission. Compared to models equipped with a 6-speed automatic transmission, the new car will achieve improved fuel economy. 2. This 9-speed automatic transmission is the 9T50, which can be applied to various front-wheel-drive platform models. It adopts a new internal structure, making the overall size of the transmission not much different from the previous 6AT. Additionally, this transmission is equipped with an energy storage device, making vehicle operation more efficient.
Last time I accompanied a friend to test drive the new LaCrosse, the salesperson specifically introduced the car's transmission configuration. The 2.0T version is equipped with GM's self-developed 9AT transmission, which has a wide gear ratio range and provides exceptionally smooth acceleration. The 1.5T version comes with a steel chain CVT, keeping fuel consumption at around 6 liters. However, it's important to note the differences between model years—the older 2.0T versions used a 6AT transmission, which can still be found in the used car market. A repair technician once told me that the 9AT version has smart shift logic, making it almost imperceptible in stop-and-go traffic, but remember to change the transmission fluid on time during maintenance to avoid valve body issues. Since last year, the hybrid version has been equipped with Buick's new dual-motor electric control transmission (ETR), which has a more complex structure compared to traditional AT transmissions.
