Original sentence: All previous DEXRON(R) specifications were replaced once DEXRON(R)-VI was introduced.DEXRON(R) is a registered trademark of the General Motors Corporation.DEXRON(R)-VI was introduced in 2005.For instance, there is now a commercially available DEXRON(R) LS Gear Oil which is designed for plate differentials used, for instance, in the Corvette.It was designed to replace all prior specifications, and is therefore backwards-compatible with applications calling for DEXRON(R) of any type.The individual specifications are individually labelled,  for example GMN-10060 (DEXRON(R)-VI).There are no valid approved products that carry the DEXRON(R) approval unless they have a DEXRON(R)-VI approval and associated license.There is also a DEXRON(R) Gear Oil which has no friction modifier and is for use in open differentials or applications such as for instance the Eaton Locker.Whilst traditionally the trademark DEXRON(R) has been associated with Automatic Transmission Fluids, more recently GM have released Gear Oils under the DEXRON(R) brand
