Shift? Shift? What is this "Shift" you speak of?? :wink: I bought mine so I wouldn't have too! But, I do kick it in to 6/OD when I reach "cruising" speed (60+) to improve mpg.Marv said:Looking at the speedometer what is the proper speed to up shift to 6th or OD gear without lugging the engine. I now shift at around 70 MPH and wonder if I could shift earlier.
