DuraDrive HD products are specially formulated for commercial and heavy-duty (HD) transmission systems where a severe duty and/or extended drain interval fluid is specified. DuraDrive HD Synthetic 668 is a licensed and approved factory fill fluid for on-highway and vocational Allison Transmission transmissions that need a TES 668® approved fluid. This is fully back serviceable to those transmissions previously filled with TES 295® and TES 468™. DuraDrive HD Synthetic Blend ATF is fully approved for extended drain application in Voith and ZF commercial transmissions. Both are suitable for use in heavy duty fleets for extended oil drain intervals. Always refer to the OEM oil drain interval recommendations for your application and service type.
