I have a 79 that i just swapped a 01 5.3/4l60e into and i am having problems getting the shifting linkage to work properly. I keep reading that minor tweaking was needed to get it to work properly but nowhere can i find what that tweaking was. My issue is that i cant get past nuetral from the column. I look down to the linkage and the rod that goes from the column to the little arm that hooks to the frame is hitting the frame. I am thinking that i can just bend it a little bit but wanted to see if any one else here had any ideas.
