How many miles on it after 7 years? Who OWNS the truck? Did you buy it new? Did you purchase an extended warranty? Have you called your local NISSAN dealer and asked? Ultimately , they will be the only ones who can say if they are giving away free transmissions.
they should. you pay extra for extended warranty, than they should. you will have to review what your warranty miles are.
