So yesterday I was driving and I had it in drive. I was on a flat road and it seems like after second gear the tranny is in neutral. The car will not go into third gear. What could be the problem? I have to drive it in 2nd gear until I fix the problem. Any help will be appreciated.

 

drive it for 10 minutes to get it hot,check the fluid,is it full,brown?

 

Sun Gear maybe?
