My gear shift is hard to move from park to drive/reverse.

LINKAGE MY BOY ...CHECK YOUR LINKAGE BUSHINGS AT EVERY POINT INCLUDING THE MAIN BIG ORANGE BUSHING ON THE LONG LINKAGE ROD, ALSO CHECK THE CAGE BUSHING THAT IS CLOSE TO THE HEADER DOWN PIPE, THAT SET UP HAS A SMALL GEAR SITTING INSIDE A LARGER BUSHING , TO DISENGAGE THE 1ST GEAR TO REVERSE...AS THE BUSHINGS WEAR THEY BREAK DOWN OLDER ORIGIONAL BUSHINGS WERE BULLET PROOF. NEW REPLACEMENTS NEED TO BE CHECKED
