69' Mustang transmission won't shift into gear...

[Paslaw]

Just bought it and gonna start working on it soon. it was driving fine until recently, then all of a sudden, it won't even shift into gear...i've never worked on cars before, i am somewhat mechanically inclined and want to start working on my new beauty...is this perhaps something i could tackle...? thanks all... for any responses...and happy new year!

Let's start with the basics, is it a manual or automatic trans?

How's the fluid level in the trans?
