It’s designed for optimum ratio progression and efficiency, and provides more accurate, quicker upshift and downshift capability. C lutch to neutral, clutch to gear ; 1-2. Downshift too quickly and you’ll. Trucks like the Ford Super Duty and GMC Sierra HD have 10-speed. 6L engine, 6R80 transmission and built between 6/1/2009 and 12/1/2009 may exhibit a shudder which is felt during low speed, light throttle acceleration between 25-45 MPH (40-72 Km/h). on the 5 speed Mack there are 2 magnetic plugs you can takeout on each side of the transmission catches the metal shavings, dont know about the others. when driven responsibly, the gas mileage is outstanding for a full size truck. I love this car.
