Allison introduces new transmission fluid

Allison has recently announced a new formulation of its high-performing transmission fluid, which improves the existing TES 295 fluid and will be introduced during 2021.


TES 668 is a modern formulation with many advantages compared to mineral-based, non-synthetic fluids. This next generation transmission fluid is specified for all Allison 1000 Series, 2000 Series, 3000 Series, and 4000 Series automatic transmissions.

TES 668 builds on the demonstrated performance of TES 295 fluid in several key areas, such as oxidative stability, antiwear performance, and friction modifier durability. These factors improve the quality of the shifts and reduce the noise, vibration, and harshness experienced as the fluid ages. Better friction performance provides more consistent clutch application – even across temperature variations and load sizes.

The robust formulation of TES 668 meets the most demanding specifications related to fluid stability, lubrication, and cold operation. This allows Allison to back long drain intervals, even when operating under heavy loads. TES 668 is specified for Allison products to ensure ideal operation.
