I have used it in my mom's '03 Altima (4 cyl) Prior to that it had a fill of Valvoline DEXIII and Mobil 1 It has been 2 years and about 30,000 km and it feels good smooth shifting (just a hint of crispness) and no banging from D to R (but that may have to do more with healthy tranny mounts) Overall no problems but then the tranny seems to be in good shape anyways
