I had the exact problem,not good news it was my clutch. I should say the electronics in the clutch .it was cheaper tp replace it than have it repaired.

I just went thru the same thing and called Eaton fuller they said some transmission need reprogrammed if you use the new updated xy shifter they said they just tell the tech to reprogram the tranny if they call with problems. Also if you call Eaton they can give you a parts no that will be the original part and you won't have the new updated shifter or any problems
