Dave1647545494 Posted February 25, 2011 Report Share Posted February 25, 2011 should have a little vacum valve on the side of the tranny check and make sure the line isn't split anywhere if it is replace the line and see what happens if it still shifts late replace the valve Quote Link to comment Share on other sites More sharing options...
