I swapped in a 4L80E along with my 6.0L a while back and haven't tried to put it into gear until now. I had to relocate the mount on the frame that the linkage rotates on, lengthen the main rod that goes to the column, and of course relocate the crossmember. When I try to put the truck into gear it makes a griding sound. Even when I try to put it back into park, it does the same thing and I have to jiggle it to get it to stop making that aweful sound. Do I just need to keep tweeking the linkage to get it to shift right? Anyone with a 4L80E swap have this problem?
