Leaving work today I got off my 94 to lock the gate--as i shifted into neutral the shift pedal traveled about 2 inches farther down! it was in neutral so I locked gate and used my toe to raise the lever. I found I could shift through the gears but also had a vibration--After getting it in 5th I found-to my dismay that I could not downshift Fortunately I live in a small rural area so I timed the 2 lights and slipped some clutch but I make the 10 miles home. There was no advanced notice to this issue--rode smooth to work this morning and shifted ok --Any ideas what to look for and what am I in for???
