Starting to get my parts and pieces together for transmission fluid change in my 2017 grand Cherokee limited v6 8 speed auto and realized it's not that easy to find a fluid for it. Internet is telling me it's lifetime fluid, some people say Mopar ATF+4 is fine. If I can use Mopar ATF that would make my live easier since that's what I use in my 01 Cummings and can change both of them at the same time.
What should I use? Is there a better fluid I can use in both of my vehicles?
