licensed ATF +4 is supposed to meet rigid standards and there in very little difference between any brand, so it is said.
Go to this site to find out if your brand is on the list, then sleep well.

aap is Advanced Auto Parts. There are discount codes and you can order on line and pick it up at the local store at great discount (20 to 40 percent).
Yea, when it comes to ATF+4, you can safely use WHATEVER fluid is the cheapest, and leave it at that.....who knows if it's a "true" full synthetic fluid....but if you're transmission specs ATF+4, I would not consider deviating from that spec
Chrysler goes through and has to "OK" every brand that states they meet ATF+4.....you can't just put ATF+4 on your bottles without consent from Chrysler from what I understand.....
BUT, what I don't quite understand, is Royal Purple MaxATF states that it "meets" ATF+4 spec.....BUT, Royal Purple Max ATF is not listed on that centerforqa site above posted
Same is true with the Amsoil, and Red Line; all of which carry "Multi Vehicle" ATF which states they meet ATF+4......but they are not listed on the centerofqa site
