I took my 300 to nissan today because my clutch was acting crazy. They said it would cost $580 just to pull the tranny to look at it. They said the ythink it might be either the clutch (which is fairly new so it should be fine) or the transmission yolk (which the throw out bearing slides on) might be cracked. My question is is $580 a bit much just to pull the tranny? Please help me on this!!!
