Shift linkage
So when I put the transmission in park then the linkage inside the cab says park and attach the linkage, I then get in the truck start it up, I put it in reverse it goes in but didn't say reverse on the selector, then natural but still didn't say the right thing , then drive, now when it goes into drive there's a thump. Aside from that trying to put it back in park there's nothing, it's like the linkage isn't pushing or grabbing
