Do all G37's have 3.7FD?
 

I been looking around and wanting to swap my diff with a G37's, but I am not sure which model G37 has the 3.69FD.... After doing lots of research I know that G37s MT and 7 speed auto have them. What about the other models? Do they come in 5 speed auto or something? and whats the FD on those?

No, more details here:

I'm selling a 3.7FD, its not a VLSD though.

Isn't the 7-speed auto a 3.3 FD? I remember I almost made the mistake of buying that one.

^Yes

EDIT: Just noticed the convertibles (6MT) come with a 3.9.
