i just drove my cummins form ct to nebraska to get a parts truck and i checked the shifting before bought it and now that ive installed it in my daily driver the 1, 3,5 gears are hard to get into and pop out if you dont hold them in. is there a ssimple solution?

I had the same problem. Mine had a screw that came loose Figure 29 on the factory manual.

I do rember it was an easy fix. I think it was page 20 of 94. I hand wrote Ball berring with an arrow. That might be it. It was 12 years ago. So take a look at the easy stuff first.
