i drive a hummer and the button on the gear shifter wont go in to let me reverse or drive or nuetral. earlier i had to slam it very hard (the button) just to get to work. is this a problem with the transmission or is this a problem within the gear shifter itself????? please help. oh and what kind of mechanic should i take it to, and about how much will it cost??
