Additional Notes

  • The Buick Envision 2.0 Turbo VVT AWD carries a service fill capacity of 5-6 liters for its automatic transaxle, reflecting the partial drain-and-fill volume typical of a routine fluid exchange without full disassembly.
  • The 2.0 Turbo VVT AWD overhaul capacity of 8.5-9.5 liters represents the total fluid volume required when the transaxle is fully disassembled, cleaned, and rebuilt from a dry state.
  • Both the 2.5 VVT AWD and 2.5 VVT FWD configurations share an identical overhaul capacity range of 8-8.5 liters, placing them noticeably below the 2.0 Turbo AWD overhaul figure of 8.5-9.5 liters.
  • The 2.5 VVT AWD and 2.5 VVT FWD variants also share the same service fill range of 4-6 liters, a wider spread than the 2.0 Turbo AWD service fill of 5-6 liters, which may reflect variation in residual fluid retained after draining.
  • All three configurations across 2018-2020 carry a 45,000-mile fluid change interval applied under severe use conditions, meaning the interval is not the standard maintenance schedule but one intended for more demanding operating environments.
  • The AWD and FWD variants of the 2.5 VVT engine share identical capacity figures for both service fill and overhaul, indicating the drivetrain configuration does not affect the automatic transaxle fluid volume in those two cases.
