Been driving the '87 442 fine this summer, more than usual. Went to drive the other day, slight whining noise when idling. Trans would not shift past 2nd. tried manual shifting still nothing. Noise was louder in second and would get louder with RPM. Checked TV cable moved okay and adjusted by pushing all the way in and stepping on throttle listening for snaps. Still won't shift out of 2nd. Please help not much driving season left. Possible sticking governor? Thanks in advance.
