King Hauler question

[REV73]

Hi everyone. today for the first time since I got it, I actually drove my king hauler, it took 8 months to acquire the funds to outfit it with electronics. my question is this, when shifting from first to second,and second to third the gears clunk a bit? is this normal? and is it best to return to neutral before climbing through the gears, or just simply toggle the stick from left to right at the speed you are already going? thanks
