Product Description
INTRODUCTION
DuraDrive HD Automatic Transmission Fluids are specially formulated to perform under the demanding severe service operating conditions found in heavy duty transmission systems. They are designed for use in commercial applications where Severe Duty and Extended Drain Interval fluids are specified.
DuraDrive HD Synthetic 668 ATF is fully approved for on-highway Allison transmissions. DuraDrive HD Synthetic 668 is the first fluid to complete Allison’s rigorous validation program, receive license approval, and be awarded Allison’s global factory fill program. DuraDrive HD Synthetic 668 meets and exceeds the TES 668™ specification and is backwards compatible for every Allison transmission that currently requires approved TES 295® ATF*.
DuraDrive HD ATFs are formulated with 99.9% pure base oils. The combination of high quality base oils and leading-edge additive systems in DuraDrive HD ATF formulations helps retain their fresh oil properties longer resulting in superior product performance.
