Dexron VI is considered the latest and greatest and is more common now. For our applications power steering system it is probably not going to be an improvement. But it is more common than Dexron III.
As I understand it, this is a combo of a naming and product specification issue stemming from deals between various parties. Dexron III was a description of a specification the fluid was manufactured to, as well as a trademarked product name that was licensed to others by GM. I am thinking ATF being used in automatic transmissions is a much bigger driver of the market than cars that use ATF in their power steering system. In any case you can use Dexron VI in place of Dexron III, but it may be more expensive since it is fully synthetic and also probably because people have to pay royalties to GM.
You may be able to find some stuff labeled Dexron III if you look hard enough. You could also check your local BMW dealer and see what they have sometimes they have reasonable prices for a quart of oil or ATF. I don't feel comfortable using walmart stuff. I suggest buying the least expensive major label ATF for the power steering. Avoid "high mileage" products, and never use dollar store fluids.
It meets the LT spec and is well-regarded by people that rebuild ZF transmissions. Note that the original fluid is dyed olive green, while the Valvoline is dyed traditional red.
The original fluid can be passed off as "dirty, burnt and worn-out" even when new. Red fluid makes it slightly harder for oil change places to claim that you need a service. I just did all four PS hoses and flushed the system last weekend on our iT. I had previously replaced the reservoir and flushed so the fluid was already fresh but I had bigger leaks than just a crack in the reservoir and bad hose ends unfortunately.
Doing the trans this weekend, but will use Pentosin ATF1 for that thought about the Valvoline Max Life, well regarded in the Audi ZF trans world--the i has the same transmission as our '01 allroad had. It would be a good idea to figure out why the fluid is low.
Hopefully topping up gets rid of the whirring noise. Jesus you guys are making this way more complicated than it needs to be. Originally Posted by e39hamann.

My car is my best example of course - had brand new load of 'basic approved' ATF.
Groaned like a mofo at low speeds in parking lots. Started throwing the 'good stuff' in and over changes the car was silent and the 'pump is gonna go sooner or later and probably sooner' is still there and running great several years and 10's of k's later.
I also throw a magnefine filter into the return line to the reservoir and that helps but I've helped a handful of guys eliminate their formerly grave steering diagnosis with this process I change it when it starts to look and smell disgusting also Damn you cheapskate bastiche, its only a single bottle too It's even a perfect use of whatever leftover high-grade ATF if you happen to have some lying around from any auto trannies in the family that's how I ended up using D4 for a while I think I don't have the exact details on GM naming issue.
So if you want to stay compliant then you have to use the new stuff. All of a sudden there are new requirements that and new "better" products and the old ones are now bad. Good info from you and jicaino on the Dexron VI being a thinner fluid I did not realize that. Recommended Posts. Report post. Posted November 30, edited. Hi, Just had a look through my owners handbook - how to topup Power steering fluid, and I couldn't find any reference to it anywhere.
