i have a g35 coupe 6MT.. it has about 45000..
4days ago i went to dealer for two problems
first problem is fuel guage problem.. car's fuel guage show me gas is not full
even though tank is full of gas. under warrant they fix it for me.. they said it's under tsb.

second problem is the noise problem.. this is a big deal..
all of sudden my car makes groaning noise in 1st gear. i'm pretty sure you guys know about slip noise. when slip light is on there is big grind(vibrate) noise. i know this is normal. but my car makes similar noise like that in 1st gear right after acceleration. right after let the gas pedal go there is a light
grind noise.. like you know.. boooooooooom or goooooooooom.. they said i have to change my clutch. wtf.. my clutch is not sliping or nothing.. and as u know i try clutch test too.. why dealer said some stupid thing? anyways
do you guys have same noise like that? please help me!! is it my trac problem? any sensor goes bad??
