Additional Notes

  • The Buick Envision (GM D2XX/D2UX) rear differential holds 0.75 liter across both the 2.0 Turbo VVT AWD and 2.5 VVT AWD configurations for the 2018-2020 model years, indicating a relatively compact rear differential unit consistent with a crossover-class all-wheel-drive system.
  • Under normal use conditions, the rear differential fluid change interval is set at 150,000 miles for both the 2.0 Turbo VVT AWD and 2.5 VVT AWD variants, reflecting a long-life fluid specification intended for standard driving patterns.
  • Under severe use conditions, the rear differential fluid change interval is reduced to 75,000 miles for both AWD variants, exactly half the normal-use interval, which reflects the accelerated fluid degradation associated with more demanding operating conditions.
  • The rear differential clutch is a separate fluid circuit from the main rear differential, carrying a distinct capacity of 0.4 liter on both the 2.0 Turbo VVT AWD and 2.5 VVT AWD models across the 2018-2020 range.
  • The rear differential clutch capacity of 0.4 liter is notably smaller than the 0.75 liter rear differential capacity, consistent with a wet-clutch pack assembly used in electronically controlled AWD coupling systems rather than a conventional open or limited-slip differential housing.
  • No change interval is listed for the rear differential clutch fluid on either AWD variant, distinguishing it from the main rear differential, which carries explicit service intervals for both normal and severe use conditions.
  • The rear differential fluid capacity of 0.75 liter is identical across the 2.0 Turbo VVT AWD and 2.5 VVT AWD engines for 2018-2020, indicating the two engine variants share the same rear differential hardware regardless of the difference in engine displacement and configuration.
