Hey fellas I got a gmc 1500 when I put it in drive it feels like my rear brakes lock up it jumps and hops makes all kinda racket... Then I can put it in neutral and it rolls the best you ever seen.... Put it in reverse it rolls fine too as soon as I put it in drive it locks back up ???? What do y'all think it is I've called gm and they say it just needs driving cause I don't drive it all the time but it seems to be getting worst
