Transmission trouble
 

Hi. So I've had my 03 350z for a few years now, and the transmission has recently taken some damage from a manhole. Other than a hole in the pan (which I've fixed) it doesn't visually seemed damaged, but all of the tranny fluid drained out when it took damage and now the clutch won't catch. Don't have many tools at the moment, but can't really afford a new one. Long story short, should I buy a rebuild kit, or try to get a new trans. Btw it's automatic
