2'nd Gear Problem

Hi,

I have problem with putting in second gear when i'm trying to do it quick. I feel like I have to push knob further than on other gears. I tried to adjust gear cables near gearbox but it didn't help. Oil level in gearbox is higher than level plug. Do you know what else could it be?

If you have adjusted gear cables, it could be your syncros on the way. Third went on mine and I just replaced the box with another. Does it feel harder to push into the gear or is it definitely further to get it into gear. 

I was afraid of syncros...

It's hard to say but i think it's further to get in into gear.

I'll try to adjust cables one more time.
