I just wanted to share my review of maxlife atf for these trucks. i didn't really think fluid brand would be a big deal but i'm a believer in this stuff. i took my truck in to a friends shop and had the tranny, coolant, and brake fluid flushed, from day 1 i have always had some harsh shifts just didn't seem normal so after we put the maxlife in its so much smoother feels like a different truck all together. i know sometimes we get in our own heads thinking oh this changed everything but i really do feel a big difference. i just wanted to share in case people have never tried this in there lightnings.
