there is a 4 and a 5, but they weren't DEX. 4 was ATF+4 by chrysler, and 5 is Mercon 5, which is ford.
The thing about dex3, is there where multiple versions over time. Without know which specs your dex3 is matching, it my not be acceptable. If you put standard dex3 in your car, you will burn up your clutches. If you use the high friction version, it is much closer to what oem recommends, but still not 100% proven.
Some propaganda:
Chrysler transmission fluids: 7176, ATF+3, ATF+4
:Obviously everyone is still ignoring the data sheet to which I provided the link. Yes, the document is very long, but the important information is found there. This IS from the service manual for Aveos:
[TD="class: T1, align: left"]Automatic Transaxle
[/TD]
[TD="class: T1, align: center"] 5.77 ± 0.2L (6.1 ± 0.2 qts) :
1.6L DOHC (AISIN 81-40LE)
[/TD]
[TD="class: T1, align: left"] ESSO JWS 3309 or ISU DEXRON III
[/TD]
[TD="class: T1, align: center"] 6.9 ± 0.2L (7.3 ± 0.2 qts) :
1.8L DOHC (ZF 4HP16)
[/TD]
[TD="class: T1, align: left"] ESSO LT 71141 or TOTAL ATF H50235
[/TD]
The table graphics don't reproduce in this format, but you can view the original for yourself (click here).
Here is another link that confirms it: "Notice : When adding fluid or making a complete fluid change, always use ISU DEXRON III or ESSO JWS 3309. Failure to use the proper fluid will cause hose and seal damage and fluid leaks." (click here).
All Aveos in America are 1.6 liter engines which have the Aisin 81-40LE transaxle. It specifies the Esso number fluid and the equivalent with which we all are very familiar, DEXRON III.
I've been quoting this in every discussion, every time this comes up, but the skepticism continues.
NOW will you believe me?

It's not that I don't believe anyone, but the dex III bottles I've found don't say they're ok for esso lt 71141. That makes me nervous. I'm more comfortable using the castrol, pennzoil, or quakerstate fluids that say on the bottle they are ok to use...
From your point of view (rabbit and thyme)....will the castrol fluid be ok to use, even though it may not be the best? I will change it every 50k miles.

The information I provided relates to the original manufacturer of the transmission (Aisin) and the official GM service manual (the European version of the Aveo, but it doesn't matter as long as the engine and transmission are identical, which they are).
My Aveo now has 10,000 miles on it and the tranny fluid is already light brownish - no longer red. That's the original fluid - never changed. By the end of next month I will drain it and replenish it with Dexron III. I'm not nervous in the least about doing it. Fresh fluid is better than degraded fluid. I am confident that the Aveo service manual (as well as the specs written by Aisin, the transaxle manufacturer) have provided the correct data for the fluid to be what it says it is.
Now if I were an aftermarket fluid manufacturer and the specs were hard or impossible to find, I would probably not publicize that information either, knowing that my more expensive fluid is much more profitable than a commonly available, generic fluid (Dexron III) that is much cheaper, but just as effective.
BTW, I change the tranny fluid in all my vehicles regularly as cheap insurance against transmission failure. Clean(er) fluid is better than dirty, degraded fluid. All my cars take Dexron III. The others are a '99 Toyota, an '89 Mitsubishi and an '88 Chevy Caprice. I buy the Dex III by the gallon, literally, and change the fluid when it is less than red. No signs of transmission failure in any of them. Note the age of these cars. I must be doing something right.
Draining and refilling your A/T fluid regularly, even though it is only a partial flush of the entire fluid capacity, is much cheaper than having a transmission failure. "Been there, done that."

I understand (somewhat lol) what you are explaining. I still don't have the comfort level though, as I'm still not familiar.
In your opinion, would the MV ATF's be ok to use? Better/worse/equal to the dex III, in you opinion?
Well, if you read the information provided and understand it, you won't be uncomfortable.
To answer your question, it will be no better, only "equal" - but at more than double the price.
Thanks, I've been trying to read up as much as I can....
I can get the castrol stuff for like just under $7/qt....so dex III is like $3.50/qt or less? I am happy with $7/qt as I am confident now it will work fine. I paid more than that for the ATF 4+ in my ram, and it took like 4x the amount of fluid! I think the aveo only needs about 4 qts for a pan drop?
READ THE DATA SHEET that is part of the Aveo manual.
Esso 71141 fluid is NOT for your Aveo!
All American Aveos have a 1.6 liter engine that takes ESSO JWS 3309 or ISU DEXRON III.
What part of that do you not understand?
look man you don't have to be a jerk. I have my manual on my coffee table right here....here's what it says....
"Notice: Use of automatic transaxle fluid labeled other than ESSO LT71141 or TOTAL ATF H50235 may damage your vehicle, and the damages may not be covered by your warranty. Always use ESSO LT71141 or TOTAL ATF H50235 labeled transaxle fluid"
The numbers you mention above are not in my manual...IN MY MANUAL IT SAYS ESSO LT71141 IS FOR MY AVEO
