OtherDescriptionText_Allison Transmission has designed extensive programs including specifications and tests to verify the quality of fluids and consequently have specific fluid and filter change recommendations. Due to field studies, changes in emission requirements, vehicle design, and operating environments, Allison Transmission can only recommended fluid change intervals for TES 668™TES 295® or TES 389® approved fluids and filter change intervals with genuine Allison filters. Should you choose not to utilize TES 668™/TES 295® or TES 389® approved fluids or non-genuine Allison filters then Allison Transmission cannot recommend a specific fluid and filter change intervals.
