first gear lock out?

ok sometimes when am at a light and my car is in neutral and i go to put my car in first gear, it wont go in, it feels like there is a way there or something, but i can put it in say 3rd gear then back to first and it will go in? any ideas>"??

This is just typical T5 stuff here. Every Mustang I've ever owned was like this. As a habbit, I now put it in 5th, then back to 1st everytime. Has to do with gear alignment or something. I think everything is ok with your equipment, just the nature of the beast!

Going into a forward gear before reverse (straight cut) is normal. Going into a forward gear before going into first is not normal.

Where is the point of engagement right now? If it's close to the floor, chances are the cable adjustment is not the issue.
