Answer
Hello Eddie,

   I have bad news for you. That's the first sign of the transmission going South. The fact that you still have 1st gear means there's still hope. It would be ideal to have the linkage to the transmission checked for problems, as this does happen. You can also do a basic check of the linkage, by going underneath the Jeep, while a helper shifts the slelector back and forth. This is a way to look for signs of wear. I hope this helps you. Let me know if you have any other questions. good luck with the Jeep! --Jeep4x4man
