Is the Envision's Transmission Dry or Wet?

[DiLucia]

The Envision 1.5T model is equipped with a dry 7-speed dual-clutch transmission, independently developed and produced by SAIC-GM. The 2.0T model uses a conventional 9-speed automatic manual transmission. The dry 7-speed dual-clutch transmission may exhibit some jerking during low-speed gear shifts, accompanied by a certain impact sensation and noise. The Envision is a mid-size SUV from SAIC-GM Buick, powered by either a 1.5-liter turbocharged engine or a 2.0-liter turbocharged engine. All 1.5-liter versions come with a 7-speed dual-clutch transmission, while all 2.0-liter versions feature a 9-speed automatic manual transmission. The Buick Envision is available in both China V and China VI emission standards, with options for two-wheel drive and four-wheel drive. The four-wheel-drive versions adopt a front-engine, four-wheel-drive layout with full-time four-wheel drive and a multi-plate clutch as the central differential.

I previously paid attention to the powertrain configurations of Buick models. I remember that the transmission setups for the Envision varied significantly across different model years. The 1.5T versions from 2014 to 2017 used a dry dual-clutch transmission, but many owners reported overheating issues in congested urban driving conditions. Later, during the mid-cycle refresh in 2018, Buick replaced all 1.5T models with a wet dual-clutch transmission, which offers better cooling efficiency through fluid circulation. Currently, the 1.5T models on sale are equipped with a 9-speed HYDRA-MATIC transmission paired with a wet dual-clutch module. As for the 2.0T versions, they have consistently used a 9-speed automatic transmission from the first generation to the present. When selecting a car, it’s best to confirm the specific model year, as the wet dual-clutch transmissions post-2018 show significantly improved reliability.

I've studied the technical differences between dual-clutch transmissions, and the wet-type design is actually more suitable for SUVs like the Envision. You see, the clutch plates in a wet dual-clutch are fully immersed in transmission fluid, providing much better cooling than dry types. It was indeed a wise decision for Buick to later equip the Envision with a wet dual-clutch, especially in cities like Beijing and Shanghai where traffic jams are frequent, as the wet type effectively prevents overheating protection. However, it's worth noting that the pre-2017 1.5T models did use dry-type clutches, and you could feel slight vibrations when idling in D at traffic lights. These older models are still available in the used car market, so it's best to thoroughly test the transmission condition during inspection.

As a car enthusiast, I learned from the manufacturer's engineers at a technical lecture that the current Envision offers two powertrain configurations. The mainstream 1.5T version uses GM's in-house developed CVT intelligent transmission, while the higher-end 2.0T model is equipped with a 9-speed automatic transmission. As for the dual-clutch transmission, it was only available on pre-2018 1.5T models. The 2023 lineup has upgraded transmission technology across the board, with the 1.5T+48V mild hybrid paired with CVT, completely phasing out the dual-clutch structure. It's advisable to check the vehicle identification plate or VIN for configuration details before purchasing.

Simply put, it depends on the model year: The pre-facelift 1.5T models before 2018 used a dry dual-clutch transmission, while the post-facelift versions switched to a wet dual-clutch, and this configuration has been maintained up to the current 2023 652T models. During maintenance at the dealership, I've seen disassembled parts—the friction plates of the wet dual-clutch are immersed in specialized fluid, with a very intricate cooling oil passage design. However, in daily driving, you might not notice a significant difference unless you're tackling prolonged mountain climbs or engaging in aggressive driving. New owners needn't worry, but if buying a used older model, remember to include transmission warranty terms in the contract.

From a technical iteration perspective, Buick has undergone a significant transmission upgrade path with the Envision model. The early dry dual-clutch transmissions did indeed generate complaints about jerky shifts, which saw a substantial decline after switching to wet-clutch versions. In the past three years, CVT transmissions have replaced the dual-clutch systems, delivering better smoothness and fuel efficiency. Nowadays, steering wheel paddle shifters also provide a manual-like driving experience. Personally, I'd recommend prioritizing post-2020 652T versions when selecting - their wet dual-clutch systems have more mature engine matching, and the shift logic has undergone three optimizations, making them significantly smoother than older models.
