OK guys i have a 2000 Sentra SE with an auto tranny(I know, I know, spare me please), but heres my question how hard would a 50 shot be on my tranny? I was thinking about the Zex nitrous system because it is only activated at WOT. I probably would not use it all the time, just for drag and the occasional beating of a ricer. So do you think it would be very bad on the auto tranny? Any help is appreciated.later.
