GM introduces improved automatic transmission fluid
Pontiac, Michigan – GM, in conjunction with Petro-Canada and the Afton Chemical Corporation, has developed a new, improved automatic transmission fluid for all 2006 model year Hydra-Matic automatic transmissions. Called Dexron-VI, the new fluid improves viscosity, shift performance and fluid durability.
In tests, Dexron-VI delivered more than twice the durability and stability in friction tests compared to existing fluids, with superior performance in pitting, foaming, oxidation and shear stability tests.
The fluid will be available through GM-authorized dealerships and service centres in summer 2005, and is approved for retrofit use in all Hydra-Matic transmissions prior to model year 2006.
