What transmission fluid is recommended for an Allison transmission?
When it comes to maintaining your Allison transmission, using the correct transmission fluid is crucial for ensuring optimal performance and longevity. Allison transmissions are known for their durability and reliability, but like any mechanical system, they require proper care. In this article, we’ll explore the recommended transmission fluids for Allison transmissions and why choosing the right one matters.
Understanding Allison Transmission Fluid Requirements
Allison transmissions are commonly used in heavy-duty vehicles, including trucks, buses, and RVs. These transmissions are designed to handle significant stress and require high-quality fluids to operate efficiently. Allison Transmission, the manufacturer, has specific recommendations for the type of fluid that should be used in their systems.
Recommended Transmission Fluids for Allison Transmissions
Allison Transmission recommends using fluids that meet their TES-295 or TES-668 specifications. These fluids are specifically formulated to provide the necessary lubrication, cooling, and protection for Allison transmissions. Here are the key options:
- TES-295 Approved Fluids: These are synthetic transmission fluids designed for extended drain intervals and superior performance. Popular brands include Mobil Delvac 1 ATF, Castrol Transynd, and Allison's own branded fluids.
- TES-668 Approved Fluids: This is the latest specification from Allison, offering enhanced performance and protection. Fluids meeting this standard are ideal for newer transmission models.
Why Using the Correct Fluid Matters
Using the wrong transmission fluid can lead to a variety of issues, including overheating, poor shifting performance, and premature wear. Allison-approved fluids are engineered to handle the unique demands of these transmissions, ensuring:
- Optimal lubrication and reduced friction.
- Improved thermal stability to prevent overheating.
- Extended transmission life and reduced maintenance costs.

What is the difference between tes 295 and tes 389?
TES 389: A mineral-based fluid similar to Dexron III. TES 389 utilizes industry-standard recommendations for fluid change intervals. TES 295: A synthetic fluid with extended drain intervals and enhanced temperature stability and performance.
Is Dexron 3 compatible with TranSynd?
Castrol TranSynd can be recommended for all vehicles calling for Dexron III/Mercon or Allison TES 295 and TES 468 ATF's suitable for bus and refuse vehicles with automatic transmissions.
What is the best transmission fluid for the Allison Duramax?
Transynd (and the other labels under which it is marketed -- like SynTran) and Mobil DELVAC are the two TES 295 fluids and are recommended by Allison. The TES 295 fluids are synthetics and give substantially extended drain intervals as well as better extreme cold and high temperature lubrication.
