You should have to press the button on the shifter as it is the gate-lock. Without it it can get bumped out of position while moving. It may just need adjusting. I assume they made no changes that would make the brake peddle depression necessary so that should be normal.

can you tell me how to adjust this

hello, i'm new here. I have noticed that when I want to shift gears with my Zforce 1000 Sport R, I do not have to press the brake pedal or button on the shifter, this may be normal.
