DEXRON

In 1993, GM released new Dexron-III fluid (GM Spec GM6417M and later GMN10055). It is generally backward-compatible with transmissions using earlier Dexron fluids or Type-A/Suffix-A fluid. However this specification failed to address a number of issues concerning long term durability such as shear stability and fluid oxidation. Dexron-III underwent a number of iterations in an attempt to address various shortcomings but was eventually replaced by new thinking i.e. DEXRON-VI.
