powertrain is the transmission and driveshafts and stuff like that anything that has to do wiht the transmission and stuff. im 99% sure that they wont cover it, but we have a 98 maxima 5 speed and a auto and we havent had any transmission problems and on the 5 speed it still has the stock clutch and it has 255,845km.
good luck with the maxima, but not like you will need it
