i did that but didnt have a second person to help. But even with the linkage bolt loose moving the shfit lever doesnt "fix" it being off. Its like the actual detent peice needs to move. But I loosened all those peices and couldnt make it move any.
I feel like if the peice I call the detent since I dont even see it at all in the service manual pointed to in green would move it would fix the indicator.
im still going through the service manual trying to find where it talks about indicator adjustment.
