Clutch Problems

I have a Eaton Fuller RTOC - 16909A which has been converted to a 13 Speed. I am having difficulty getting it to come out of or to go into some gears. This seems to be random. My clutch brake isn't working either. I have to turn the engine off to get it to go into first. I recently had the clutch adjusted after I noticed it slipping. Is it possible that it was adjusted too tightly and the clutch isn't releasing properly. Or what else could the problem be?

 

1.5" ......

 

It began slipping badly and the clutch had no freeplay at all. I had it adjusted and everything seemed to be OK, just took a couple of days to get used to it after the adjustment.

Now it is not slipping, but the clutch brake is not working and is harder to put into or out off gear. I can bump the fuel pedal and it will slide into gear, nothing like it was before.

I have, since, installed the Bully Dog, but I drive 57 MPH everywhere I go and have not over torque the engine at all.

 

No! It is not slipping! It was and was adjusted. Now, a month after it was adjusted, it is hard to put into some gears and the clutch brake is not working. I think when they adjusted it it had more than 1.5."
