My Mustang is an automatic. The shifter in the console sticks when changing gears. At times, I have to keep it half way into another gear or else I hear grinding or the car won’t go into gear. Is it my transmission or my console?

Year ?

Cable or cable adjustment.

Probably the shifter is out of adjustment or there is something broken in it. It is hooked to a cable that moves a lever on the side of the transmission. Have it looked at immediately by a good shop. This is not good for the longevity of the transmission. Keep this up much longer, and it will be the transmission ($$$$$$).
