    10 speed auto, which I hate. 3.70 rears, How do you think my mileage will compare to 10 or 13 manual?

    You will always get better mileage in a manual due to less resistance through the transmission as well as you being able to keep the engine in its best operating zone easier.
     
    drivenmecrazy Thanks this.

    "less resistance through the transmission" ?

    Isn't the autoshift just a regular 10 speed with a robot shifting it ? The transmission drag would then be the same.

    Thanks

    3:70 gears? What motor, truck, what year and what are you hauling?

    Yes this is true, except the shifting is done by computer control electronic soleniods. The autoshift has a clutch pedal and the ultrashift is a centrifugal clutch (no pedal).

    auto's will skip gears just like a manual driver, depending on load also you can manually shift them also, the autos are the future because of better mileage for most drivers and a big reduction in maintinance cost. at least for the big companies, the only real negative is a higher intial cost

    I have an auto shift that I have to run manually after every restart to retrain the computer to get the shift points set right. If i don't it will run the engine up to 2100 rpm before shifting and shock load the drive line and my back

    being that I am always trucking from and to the UP of Michigan, I will stick with the 10 Manual. I can control it better in the snow.
