Hello, My '69 GT14 trans. (Sundstrand) has developed a leak where the fwd/reverse slide linkage goes into the trans. I want to go into it to stop it. Has anyone else had this problem? Can parts be purchased at any auto parts store or Toro dealer? I'm guessing maybe it's an O-ring? Is there a kit for this, does it need any particular seal? or can I just find things readly available? Thank you for your help. Rick
