When the temp drops below freezing my gear lever sticks until it's warm. I mean nearly impossible to move. Even side to side let alone into a gear.

Any ideas what part of it is sticking and what to do about it?

 

your tranny fluid hahaha. seriously though its your tranny fluid thats getting thick thats preventing proper shifter movement

 

If it's an aftermarket clutch it might be dragging a bit, I know mine did until properly bled of air.

 

99% chance this is what's going on, happens to me.

 

its been down to -15 here, its harder to shift, but not sticking at all.

 

-35 degre celsius here and stiff a bit but no major issue... alot of noise in the suspension on the other hand...
