last week i pulled into a parking spot went to put in reverse and it wouldn't go in . it never made a grinding sound or gave me a lick of trouble before .1st thru 5th go in and work fine , which has me thinking its a linkage probelm . its is a stock shifter . i've never taken 1 apart . has anyone of my fellow stangers had this probelm ? if so what was the issue and how did you fix it ? thanks for any insight you can gave me .
