Maintenance Schedule and Best Practices. This specific formulation is designed to meet the exacting requirements of modern GM transmissions, providing the necessary friction modifiers for electronic shift control and protecting against the high stresses of daily driving.
While Dexron VI is suitable for many modified engines, high-torque applications may benefit from a high-performance synthetic fluid. Using an older, non-compliant fluid can lead to harsh shifting, slipping clutches, and potential damage to the valve body, negating the performance gains from any other modification.
