Just exactly why are there so many different types of this stuff?
Type F,Mercon V,Dexron 1,2,3,4!
Then,each engine has to have a specific type for year it's made?
Or,can I just put my tractor fluid in them?
Somebody try to explain this to me please!
Thanks,Mike.

Your engine doesn't need any transmission fluid.

LOL...literalist

Mike, what year/model/transmission?

The Dexron stuff all the older numbers are just that, older. They get phased out as new specifications evolve, and the new stuff replaces the old. Dexron VI is current and you would use it in anything that specifies a previous version of Dexron fluid. The newer transmissions require it as they have been designed in a way that has special fluid needs, just the same as newer engines have different oil specifications.

Not all transmission manufacturers use the same component parts in clutches, servo's, bands, other specific parts, and with them, comes individual fluid "builds" to work with all the different parts. So, what works in a GM automatic, won't usually work with all the different components in a Ford automatic.

Well,I have lot of them!
350's,400's,700-r4's,4L60 E,4L80E and,a 200r.
Plus the wife's Cavalier and mom's Mercury.
When I see a new type come out,makes me wonder if I'm using the right type or do I need to change?
I'd just as soon continue using what I've been using instead of having more types to deal with.
I've a 99 GMC that's been getting Dexron 3.But,I read that's not correct for transmissions newer than 95.
That's the reason for the post.
Mike.

I have no idea what you're talking about :-)

Is Dexron III not still widely available? I wouldn't jump to the synthetic stuff unless I had to. Edit: I see GM only supports VI, but other manufactures still market unofficial fluids that meet the standard.

Dextron III is probably what it came with. I don't think Dextron VI was a thing until the 2000's.....Wikipedia says it wasn't factory fill until 2006.

Dexron is backwards compatible all the way back to "Type A" transmission fluid from the 50s.

In other words, if your vehicle came with Dexron of any kind, or Type A, the latest Dexron is just fine for it.

Older Fords use "Type F" which is different stuff, some used it to get a GM transmission to shift firmer.

Later Fords use "Mercon", and there are fluids that meet both Dexron and Mercon specs.

Now foreign stuff is another matter.

I've considered that, but have never had the guts to do it.

Good lord I tried it but a Shovelhead can't keep that slippery fluid inside the case. Wanna talk about a mess!

I switched to open belt drive after all that...
