Spec-V Reverse
 

I just bought a 2003 Nissan Sentra SER Spec-V. For some reason, 90% of the time I am unable to put it in reverse. I'm having a huge problem with this, maybe because it's a 6-speed. I've tryed double clutching, straightening the wheel before I put it in gear, putting it in first gear before reverse, pulling forward a bit before putting it in reverse and nothing seems to work. I don't know what I do differently when I am able to put it in gear. Plus, I've only been driving a standard for about 6 months.

Does anyone know what I'm doing wrong or not doing? Is there a trick to it or something? PLEASE HELP ME!!!!!
