While using Redline Synthetic Gear Oil, we have realized a tremendous improvement in the smoothness of shifting across the board, but especially when the trans is cold. It is the only gear oil you should put in your Bus, Vanagon, or Eurovan manual transaxle. We also recommended it for use in all differential sections for Bus, Vanagon, and Eurovan automatic transaxles.
