Welcome to Red Square!!!

 

Download this manual. it has diagnostics. 

 

First would be to check the linkage.  D linkage is complex and can slip out of adjustment

 

 manual will next send you to the reverse check valve on the pump.  The plug can be very difficult to remove.  I might skip ahead to the reverse acceleration valve on the hydro motor it is easier to deal with.

  i hope your issue is in the control linkage.  the other two possibilities are significant work.  Hope yo have a warm place to work...kind of cold here in PA right now.
