2nd Gear Problem

[EVRONE]

So I just Swap my old clutch for a entirely brand new now.
List of things I changed just for reference.

Clutch, drivetrain, flywheel, slave and master cylinder, throwout bearing, transmission and differential oil redline.

The problem is that my 2nd gear won't go in at all, and every other gear goes in perfectly in. When I shift from 1 into 2nd it'll idle and hess and won't go in at all. I don't think it could be my transmission since my old clutch accepted all my gears.

any advice on what the issue could be? I'm hoping I missed something when I installed the new clutch.

You may want to try a pedal adjustment. you can find this in the FSM, you way also want to bleed the slave first and re bleed the master.
