In the past, when our input shaft tip was shot like this, we’ve either just run it or pulled apart another transmission for a new input shaft. Since NV3550s don’t exactly grow on trees, we were resigned to running the worn shaft. Then OC Trans told us they just re-tip them. The new tip is hardened similarly to a bearing race, whereas the old tip wasn’t. If we ever pull this tranny out again, the tip should look just like the “after” shot.
