Although the GM DEXRON III-H specification license was revoked in 2011, many vehicles requiring this type of automatic transmission fluid (ATF) are still in operation today. Compared to its predecessor, DEXRON III-G, DEXRON III-H features an enhanced additive package with an improved friction modifier and a more oxidation-resistant Group II base oil. These advancements provide superior friction stability, enhanced anti-shudder performance, improved foam control, and extended fluid life.

Due to its versatility for all automatic transmissions, both with and without a controlled torque converter lock-up clutch, oil with an ІІІ-H level remains one of the most popular transmission fluids on the market.
