The wear is the tapering of one end of the gear teeth slightly. The solution is to replace the part but that part is becoming rare since it often needs to be replaced. I imagine the parts for your trans will be even harder to find. This blog below has a good picture and explanation. http://chev235guy.blogspot.com/search/label/Jumping%20out%20of%203rd%20gear | | |
