Frequently Asked Questions
Is TES 295 synthetic or conventional?
TES 295 is a fully synthetic specification. All TES 295 approved fluids must be synthetic to meet the extended drain interval and thermal stability requirements set by Allison Transmission.
Can I use Dexron III in an Allison transmission?
While older Allison transmissions accepted Dexron III, current models require TES 295 or TES 668 approved fluids. Using Dexron III in a transmission that requires TES 295 may void the warranty and lead to premature wear.
What is the drain interval for TES 295 fluid?
TES 295 allows extended drain intervals of up to 300,000 miles (480,000 km) or 4 years in on-highway applications, compared to 25,000 miles for conventional ATF. The actual interval depends on the transmission model and operating conditions.
