My mt-82 problems

Hi guys, new on the forum.

Sorry if this is just some new mt-82 post hahah.

I have a 2015 with a roush supercharger. Stock shifter, spec carbon clutch.

Recently, when the car is cold and moving, going into both gears 2 and 4 I get some sort of click with some vibration. Not quite a grind, but definitely not the normal notchiness of my mt-82. When the car warms up, it seems to go away, except evey now and then on a high rpm pull going from 3-4. The car does not do this when stationary.

synchro problems? Something else?

thanks for your input!

Anybody?
