As the title says, I think that it what's causing me to not be able to drive in first gear. If I sit in neutral and push the clutch in, it feels the same in every gear. However when I start to go forward, and release the clutch it feels like the shifter is pushing back at me and it won't let me go into first gear. If I am able to get it into first gear once going if I slow down it will pop out of gear. Any help would be greatly appreciated.
