Anybody know what would cause my shifter to not want to center itself from 1st/2nd position? It comes back to center from 5th but the other side is just sort of seems stuck. The shifter seems to go right into the top of the tranny from the underside and on the inside I gave up after I discovered the dash had to come apart to get any deeper into the shift boot area. IS it a spring or just a lube problem?
