im a huge fan of synthetic, but theres a problem, how to get the fluid out of hte torque converter. some early X's have a plug in the torque converter to get the fluid out, but my truck doesnt have it, so id have to get it power flushed out. some people say power flushing is bad for the tranny and some says its fine. personally i dont have the time to drive to the closest place around here to do it (and theres no way i would take my truck to the dealership for it.) not to mention that power flushing is expensive, so im just gonna put the mercon stuff in my tranny, actually im doing it next week.
heres the deal with all synthetics, they help longevity, but that doesnt mean that if you dont use synthetic stuff your truck is only gonna last a year, heh.
my advice, if you could do the synthetic swap, do it (with mobil 1 fluid), but if you cant do it, dont lose sleep over it.
