What Type of Transmission Does the Buick Envision Have?

[VonNoah]

Buick Envision has two types of transmissions: the 1.5T model uses a dry 7-speed dual-clutch transmission, independently developed and produced by SAIC-GM, while the 2.0T model uses a conventional 9-speed automatic transmission. Below is some relevant information: 1. Dry Clutch: A clutch that uses air for cooling is called a dry clutch. In use, the clutch should engage and disengage smoothly and easily, and should not overheat even when operating under semi-engaged conditions for short periods. 2. Dry clutches, because they lack the resistance of oil, generally engage more quickly and with greater force. Also, since there is no oil for cooling, dry clutches are usually exposed to dissipate heat.

The Buick Envision comes with two types of transmissions. The 1.5T model uses a 7-speed wet dual-clutch transmission, which is fuel-efficient in city driving but may have slight jerks at low speeds. The 2.0T model is equipped with a 9-speed automatic transmission, offering smoother acceleration. I’ve personally driven my friend’s 2.0T version, and the gear shifts are almost imperceptible, making highway overtaking particularly stable. Older models used a 6AT and dry dual-clutch, but the current versions have largely improved. Regular maintenance is crucial, especially for dual-clutch owners—transmission fluid should be changed around 60,000 km. Choosing the right transmission makes a big difference in the driving experience. If the budget allows, I highly recommend the 9AT version.

As a long-time Buick owner, the transmission of the Envision depends on the specific model. The 1.5T is paired with a 7-speed dual-clutch, which is sufficient for city commuting and offers low fuel consumption. The 2.0T with the 9AT drives like a German car, with more gears and lower RPM. During the test drive, it was noticeable that the 9AT downshifts faster, dropping two gears immediately when the throttle is pressed hard. The maintenance manual states that the dual-clutch fluid should be changed at 50,000 kilometers, while the 9AT can be extended to 70,000 kilometers. Last year, GM also upgraded the software for the 9AT, significantly reducing the jerky shifts. When buying a used car, be cautious: the dry dual-clutch before 2016 had a high failure rate, but the current wet version is much better.

Having repaired numerous Envisions, transmission issues mainly focus on three points. Firstly, the older dry dual-clutch models are prone to overheating, causing gear-shifting hesitation. Secondly, the 9AT torque converters tend to leak oil, requiring seal ring replacement. Thirdly, dual-clutch electronic control units have high failure rates. The new 1.5T models with wet dual-clutch have better heat dissipation, while the 2.0T 9AT versions are generally stable. Recommend checking transmission fluid every 40,000 km - replace immediately if it appears black. If the transmission clunks during hard acceleration, it's likely due to worn engine mounts. Never underestimate maintenance - a simple fluid change can save tens of thousands in repair costs.
