I've read a few posts here and there stating that the Amsoil Multi AFT is not a good choice for Chrysler vehicles that require ATF+4. Why this is, I'm not sure. What is the thoughts on this? Amsoil's site shows a comparison of the ATF+4 and Amsoil ATF protection after 100k and a tear down of the...
I've got a 2021 GMC Canyon with the 8L45 and its first transmission fluid change isn't too far away. I was planning on Mobil 1's LV ATF HP which GM uses for the transmission TSB's as the Dexron HP wasn't up the task. I've recently become a fan of @High Performance Lubricants motor oils and...

ATF+4 is pretty much a dealer item. From what I understand there is difference and it may not be a good idea to try to substitute ATF+3. Call around to your local Chrysler,Dodge and jeep, dealers for the best price.
MaxLife ATF looks like a competitor to Amsoil and it is actually certified for use in Toyota Aisin transmissions, but it just doesn't get the same level of rave reviews and people claiming it fixed existing issues. So I still think it's pretty much between OEM Toyota WS, Amsoil SS ATL, or Idemitsu's synthetic WS.
