- Backward compatible with previous Dexron automatic transmission fluids and can be used as a much-improved replacement for older vehicles/transmissions originally using previous Dexron fluids
- Improved performance over previous Dexron fluids in: friction durability, viscosity stability, aeration and foam control, and oxidation resistance
- Potential to enable improved fuel economy and longer transmission life
- Provides for extended drain intervals. Provides consistent shift performance, even in extreme conditions.
Released in 2005 for the 2006 model year, an updated version of Dexron transmission fluid, Dexron 6 was developed in a joint venture between General Motors and Ford upon the release of a more modern 6 speed automatic transmission. For GM, this was part of the release of the new 6L80e transmission.

Dexron 6 Transmission Fluid Questions
Is Dexron 6 Discontinued?
Dexron 6 is not discontinued and it still readily available and easy to get.
What Is The Best Dexron 6?
In our opinion, the best Dexron 6 transmission fluid is AC Delco. Since all Ac Delco is factory specified and is still supported by General Motors, it is the most recommended Dexron 6 transmission fluid.
If you cannot find Ac Delco Dex VI, there are plenty of aftermarket fluid manufactures who offer Dexron 6 that meet factory specifications. If you are in a pinch and can’t wait for factory recommended Ac Delco Dex 6, you can always go to your local auto parts store to find a suitable aftermarket replacement.
What Transmission Fluid Replaced Dexron 6?
Dexron VI is still very common in many applications, General Motors has updated the specifications since its inception with Dexron ULV and Dexron HP.
What Year Did Dexron 6 Come Out?
Dexron 6 transmission fluid was introduced in 2005 as Dexron VI and replaced its predecessor, Dexron 3. GM started to use Dexron 6 in factory vehicles starting in the 2006 model year.
How Much Dexron 6 Do I Need?
The amount of Dexron 6 transmission fluid needed for your application varies, so it is best to consult your owner’s manual. In most cases, reading the transmission dipstick will give you and idea how much fluid you need when you do routine maintenance.
What Temperature Does Dexron 6 Fail At?
Like all transmission fluids, Dexron 6 is best when it’s temperature is between 160-200 degrees F. This common range is best for longevity of both your transmission fluid and transmission itself. The below transmission fluid chart shows how long transmissions last when fluid reaches various temperatures.
What Is The Difference Between Dexron 3 and Dexron 6?
The main difference between Dexron 6 and Dexron 3 is that Dexron 6 is classified as a synthetic fluid and Dexron 3 is not. Dexron 6 has more up to date fluid properties which allows for a longer fluid life and is much better at dealing with higher temperatures. Since Dexron 6 is backwards compatible, you can use it in Dexron 3 applications.
Dexron 6 has a lower fluid viscosity than Dexron 3, but can be used in Dexron 3 applications.
Can Dexron 3 Be Mixed With Dexron 6?
In many cases, yes, Dexron 6 can be mixed with Dexron 3. Since Dexron 3 is used in older applications and Dexron 6 is “backwards compatible” GM suggests that you can use Dexron 6 in most Dexron 3 applications.
Depending on your situation, it would be best to use one or the other in your transmission. However, if your transmission’s recommended fluid is Dexron 6, you cannot use Dexron 3 in it.
What Happens If You Put Dexron 6 In A Dexron 3 Transmission?
If you put Dexron 6 in a transmission that calls for Dexron 3, nothing serious will happen. While Dexron 6 is backwards compatible with Dexron 3 transmission fluid, it’s often recommended to use one or the other for the best results.
What Color Is Dexron 6?
Dexron 6 transmission fluid is a bright red when new and should be a similar color if your transmission is maintained properly. The below transmission fluid color chart shows common transmission fluid colors depending on use and give you an idea of what to look for over time.
Can Dexron 6 Be Used In All Automatic Transmissions?
Dexron 6 is a common transmission fluid, but no, it cannot be used in all automatic transmissions. It’s always best to consult your vehicle’s owners manual to learn what transmission fluid is recommended for your application.
Can Dexron 6 Be Used As Power Steering Fluid?
Yes, it is common for transmission fluids such as Dexron 6 to be used as power steering fluid. The two fluids are similar and both work in power steering systems.
Where Can I Get Dexron 6?
Dexron 6 is easy to find both online and at local auto parts stores. Because of this, you can quickly get as much as you need.
How Much Does Dexron 6 Cost?
With Dexron 6 being easy to get and readily available both online and at auto part stores, the cost is not high. While Dexron 6 might cost a little more than Dexron 3, it’s not that significant of an increase.
For the cost, if you have an application that calls for Dex III but will allow for Dex VI, use the slightly more costly Dex VI since it’s a more durable transmission fluid and can handle more abuse and offers a longer maintenance interval.
