I think what he means by doing a straight H pattern is that when coming out of 1st going to 2nd he has to sorta go towards reverse then to 2nd.

I had a 63 1/2 ton that did this and it would get stuck. I had to crawl under the tuck and manipulate the shifter arms and get it unstuck. The shifter linkage parts were worn out.
