Choosing between two transmission fluids can be difficult especially when you have little or no knowledge about your car transmission. You can fix this problem by acquiring some basic knowledge of Dexron VI vs transynd transmission fluids types and their properties.
In this article, we will cover the major differences and features of these fluids as well as some examples of both. We will also answer some of your frequently asked questions.
Dexron vi vs transynd: features comparison
Before diving into the differences between these two transmission fluids, you need to understand TES295 and TES 389 fluids. TES 295 are transmission fluids that have longer drain intervals and less maintenance compared to TES 389 which is a mineral-based transmission fluid with shorter drain intervals. Only Dexron III falls under TES 389, making Dexron VI an entirely different fluid.

| viscosity | Retains viscosity better | Poor retention of viscosity |
| Drain interval | Longer drain interval | Somewhat shorter drain interval |
Features of Dexron VI vs transynd transmission fluid
Understanding the individual features of these fluids will give you a better insight into which one is best for your vehicle. We will cover the compatibility, viscosity, and drain intervals of both fluids to determine which is better.
Compatibility
GM initially bought Allison and always recommended Dexron VI as it is was licensed by this company. However, Allison was later sold out by GM and Allison recommends transynd fluid. Transynd is more compatible with all of Allison’s transmission because the fluid was manufactured by the company, but Dexron VI is compatible with some of Allison’s transmission but not all.
Viscosity
Transynd was manufactured to replace TES 389 fluids that had a poor ability to retain fluid viscosity. Transynd was relatively better than TES 389 fluids, but Dexron VI has a higher ability to retain viscosity.
Drain interval
Transmission fluids have a different life span and apparently, Dexron VI transmission has a longer fluid life than transynd fluid. The drain interval of transynd fluid usually ranges from 25,000 to 50,000 miles while the drain interval of Dexron can be up to 100,000 miles.

| cons | Might make your transmission slip | Poor viscosity retention |
Frequently Asking Questions
Is transynd compatible with Dexron VI?
Transynd transmission fluid is approved by Allison and GM making it compatible with Dexron VI which is equally approved by these two brands. You can mix transynd and Dexron VI as there will be no adverse effect, mixing them will improve the drain interval allow it to stand between 75,000 to 100,000.
What transmission fluid is compatible with TranSynd?
A fluid that is compatible with transynd should be approved by GM TES 295 and TES 389. Transynd is highly recommended for vehicles that use TES 389 fluids like Dexron III and Mecron, this is because it has a higher drain interval.
Can you use transynd for power steering fluid?
Yes, you can! A power steering pump is a hydraulic system just like the transmission so power steering fluids and transmission fluids are both hydraulic fluids. Transynd is known for being a good substitute of power steering fluid for your power steering pump transmission fluid is superior to power steering fluid as it is fully synthetic and contains additives, the latter may lack in these areas making it unsuitable to be used as transmission fluid.
What can be used in place of Dexron VI?
Dexron VI is superior transmission fluid and to substitute it, you need an equally superior fluid. ATF + 4 are the best substitute for Dexron VI. You can also replace this fluid with others that are approved by GM TES 295.
Conclusion
This article has covered everything you need to know about Dexron VI vs transynd fluid. They are both different in terms of compatibility, viscosity, and drain interval. Transynd can be used for all Allison transmission while Dexron cannot, it can also be used as a substitute for power steering fluids.
To replace any of these fluids, use a different one that is approved by TES 295 and TES 389.
