Additional Notes
- Both the 2.0 Turbo VVT AWD and the 2.5 VVT AWD configurations of the Buick Envision share an identical transfer case fluid capacity of 0.65 liter across the 2018-2020 model years.
- A capacity of 0.65 liter is a relatively small fill volume, consistent with the compact transfer case units commonly found in crossover AWD platforms such as the GM D2XX/D2UX architecture.
- The capacity figure of 0.65 liter applies under normal use conditions for both engine variants, meaning the specification reflects standard operating service rather than a post-overhaul or first-fill scenario.
- No variation in transfer case fluid capacity exists between the turbocharged 2.0-liter and the naturally aspirated 2.5-liter engine configurations, indicating a shared transfer case unit across both drivetrains for the 2018-2020 period.
