Well, Ive been showing the honda's what older diesels can do, and ive been doing some pretty harsh shifting. When i got the truck it grinded a little bit going into 3rd. now i can get er to grind in 2,3,and 4. ...5 spd powerstroke..Question is, should i just throw some new blocker rings in and call it good or??? still has the DMF which sucks. What are my options here?
