type of transmission fluid
The most universal and acceptable modern ATF for your vehicle is Mercon-V (Mercon 5)
Thank You for your speedy answer.
Umm no gm car takes mercon v, that is a ford trans fluid, gm vehicles take dexron/mercon III, starting 2005ish, gm patents ran out on the III so they came out with an updated fluid dexron VI which they suggest you switch to, so you can use the III or the VI, mercon V is only for a few certain ford cars.
I beg to differ but the key word I used was "Universal" and no, it isn't designed for just certain fords. I happen to have read the label on the 55 gallon drums we use to service out fleet of over 1700 cars and light trucks.
Yes their are plenty of universal trans fluids and some say they work for mercon V and dex/mercon III, gm doesn't support the use of those universal fluids. Find me a universal fluid that will work for DEXRON VI which is what GM recommends in most of their cars, old and new. Different types of trans fluids are different viscosity just like engine oil, so using universal trans fluids can be just like using the wrong weight of engine oil in your car. It may "work" but certainly is not the best option. Next, MERCON V was developed BY FORD FOR FORD. A pic of the back of a MOTORCRAFT (FORD BRAND) bottle of mercon V is provided below for proof. Also, GM has a TSB out that suggest nothing but DEXRON VI be used in any car requiring dexIII or dex VI. The TSB even suggest NOT to use the DEX III anymore for any vehicle. Therefore universal fluids that say they work for dex III is NOT suggested by GM. This is because the patents expired on dexIII meaning there is no regulation anymore on its makeup and companies are not required to add the same friction modifiers to it anymore because there is no patents on it. I work at GM dealer so I service millions of cars, not just 1700. In a nutshell, a lot of things will "work" but I would rather use what is "recommended"
