Dexron is the trade name for a group of technical specifications of automatic transmission fluid created by General Motors (GM). The name is a registered trademark of GM, which licenses the name and specifications to external companies which manufacture the fluid and sell it under their own brands. GM has upgraded the Dexron specifications over the years; newer fluids are generally but not always backward compatible with previous Dexron fluids. The current fluid is Dexron-VI, introduced in 2005.

Originally the Dexron name was associated exclusively with automatic transmission fluids, but more recently GM has released Dexron-branded gear oils. The brand name is commonly mispronounced as "Dex-tron".
