No matchan, The road works fine even without the lever can move the road when i press the top button of it without any jagging. Its the shift knob which is broken. the inside plastic parts which holds the spring is broken. I checked with Mazna, what they said is have to check if some other shifter can be fixed or can try to mold the inside plastic. Hoping to look for some other brands just in case if they fix. Problem solved. Thanks
