Have a 2008 duramax that would not shift into reverse this morning.acted like had huge stall converter to move forward and threw codes po761 and po766. Tried again tonite and everything acted normal and cleared codes. Any suggestions on how to trouble shoot these 2 solenoids? Thanx I am new to the diesel world and really enjoy this website....jw
