Hey I know this is an old thread but I have the same issue in my 91 yj but the other day it gave out and stopped the Jeep in reverse and I could not get it out of gear even with the Jeep turned off I did get it out of gear and I have gears 1-5 still but reverse bonds up now and you can feel the shifter twisting so long story short I was wondering if anyone found out what the issue is and could let me know
I appreciate all the help I can get thankyou
