Is the Envision equipped with a dry or wet clutch?

[VonEden]

The Envision is equipped with a dry clutch. A dry clutch uses air to cool the clutch, requiring it to engage and disengage from the power source smoothly and operate under short-term partial engagement conditions without overheating. The Envision is a mid-size SUV under SAIC-GM Buick, with exterior dimensions of 4694mm in length, 1839mm in width, and 1686mm in height, and a wheelbase of 2750mm. It is powered by a 1.5T turbocharged engine paired with a 7-speed dual-clutch transmission, delivering a maximum power of 124 kW and a maximum torque of 250 Nm.

The Buick Envision uses GM's in-house 9AT transmission, which is neither a dry nor wet clutch design. Dual-clutch transmissions are the ones categorized as dry or wet - dry types like Volkswagen's DQ200 rely on air cooling and can overheat in traffic jams; wet types are immersed in transmission fluid, offering better cooling but with a heavier structure. The Envision's transmission actually adopts a traditional torque converter configuration, with gear shifts accomplished through planetary gear sets and clutch plates. I've driven my friend's older 1.5T model and could feel the transmission seeking engagement points during initial acceleration, though downshifts were quite crisp. If you're genuinely concerned about clutch longevity, the real focus should be avoiding frequent launch starts, especially avoiding prolonged partial clutch engagement during summer hill climbs.

The wet and dry clutches fall under the category of dual-clutch transmissions, but the Envision lineup does not use a dual-clutch system. Since its 2018 facelift, all models have been equipped with the 9-speed HYDRA-MATIC transmission, which is essentially an automatic transmission with a torque converter. I remember once seeing a disassembled older Envision in a 4S shop's maintenance bay—golden transmission fluid was spilled all over the floor. Dual-clutch transmissions don’t use that much fluid. A wet dual-clutch is like a steak soaked in oil, while a dry one resembles teppanyaki. However, the Envision’s transmission is more like a pressure cooker, relying on hydraulic pressure to shift planetary gears. In heavy traffic, this transmission can occasionally hesitate, but its durability is far superior to early dual-clutch systems.

Here's a little-known fact: The first-generation Envision 1.5T did use a 7-speed dry dual-clutch transmission, but owners reported noticeable low-speed jerking. Later, GM decisively switched the entire lineup to 9AT, and now even the 1.5T models come with 9AT. Traditional AT transmissions don't differentiate between dry and wet types—they rely on transmission fluid in the torque converter to transfer power. My neighbor's Envision has clocked 120,000 kilometers without any transmission issues, though he did complain about spending over 2,000 yuan on a transmission fluid change—a price that could buy three sets of clutch plates for a dry dual-clutch transmission.

This is a common point of confusion. Dual-clutch transmissions are categorized into dry and wet types—dry ones have simpler structures but fear traffic congestion, while wet types offer better cooling at the cost of added weight. The Envision's 9AT is a completely different system: it uses a torque converter between the engine and transmission, relying on transmission fluid for smooth power delivery during starts. Last time I helped a colleague inspect a used car, we found oil seepage around the 2017 Envision's transmission oil pan. The mechanic said it's a common issue. Still, compared to same-year models with dry dual-clutch transmissions, at least you don't have to worry about the burnt smell of a fried clutch.

I often see people in the forum worrying about this. The current Envision's 9AT is not a dual-clutch structure, so naturally, there's no distinction between dry or wet. However, I'd like to remind all owners that the transmission fluid needs to be changed at 60,000 kilometers, and the original fluid specification is DEXRON HP. I once saw an Envision at a repair shop that didn't change the fluid on time, and the removed transmission filter was clogged with metal shavings. Although you don't have to worry about clutch wear, if the torque converter's lock-up mechanism fails, fuel consumption can skyrocket to 15 liters per 100 kilometers. If you're really concerned, you can install a transmission fluid temperature gauge; if it exceeds 120°C, you should stop the car.
