    torque output in 5th gear?!?!? the engine will have the same torque in all gears... torgue is to do with the engine pulling power, not the g box.... or do you mean todo with gearing ie overdrive???

    torque at the wheels will be reduced significantly at you are not only dividing the RPM by the gear ratio and FD ratio(and effective wheel/road ratio). but you are also dividing the effective torque at the wheels by the same variables

    say 5th gear is 0.8 fd is 4.0 (for examples) you will have an effective ratio of 3.2 so 100ftlbs of engein torque will be 31ftlbs

    but its good for crusing to reduce fuel consumption



    thats a very very rough outlook on it. get the bosch automotive handbook (blue bible!!!)

    in the 4th edition of the blue book look on page 555 for the tractive force/speed diagram

    or search google for that very title
    or the "equilibrium relation between drive forces and tractive resistance"

    gotta think out of the box

    also "an engineering data book" (thats the title) is fantasticly handy too


    and if your really stumped www.howstuffworks.com is a good starter/refresh
