I had read a lot of threads about 5th gear jumping out but I still have a question. I replaced the syndrome and shift collar which were both worn and it still jumps out of 5th at random times. I couldn't see anything wrong with 5th gear itself just a little wear on the shift fork,which I did not replace. I found the reverse spring and ball to be weak so I shunned them up and that somehow helped the 5th gear a little bit. Is there another place that detente 5th gear? Any suggestions on my evidently common problem?
