Or if the radiator has already been replaced no need to do the bypass. I have personally done a bypass and flushed the fluid on that model year.
Too Late for that. The previous owner had the heat exchange crack and coolant went into the tranny 2 years ago. Had it flushed with new rad, and so far it seems fine, however is there any way to really know if some damage was done? Apparently Nissan has some extended warranty on the transmission, if its under 90K Miles.
