2003 350z won't shift into third gear
 

I have a 2003 350z with over 100k miles and just recently the car won't shift into third gear. When i put the stick into third it is as if it is still in neutral. All other gears work fine and clutch seems to be in OK condition. Don't have a clue how this happened, anyone have any insight?

Transmission problems on '03 cars are not that uncommon. Time for a new one.

Time for a new tranny.
