stuberger, Bluegrass, i opened up my tranny to check with the exploded view in the manual just to see if any thing missing or worn away!!
And found a small piece of metal that looks like its ether come off the top of a bearing or is a bit of shim,
Its about 1/4 mm thick by 10mm round have taken it out and swapped over the switching forks,
its still the same if the trucks not moving it has problems fully engaging
