    You shift at the same RPM in each gear unless you use progressive shifting.

    Then you will need someone else with experience in that to explain. Best I know you shift at lower RPM's in lower gears to keep the RPM's down and conserve fuel.

    What is it you are trying to accomplish with this question? I don't think any/most of us understand where you are trying to go.

    Instructor's at the trucking school I attend gave us this question as home work, I have tried every computer site this computer can reach. I have ask this question as simple as possible, now I will brake it down. Is there anyone who know the answer or can direct me to a web site to answer this. What is the Lowest MPH and Highest MPH you can do in each gear .(NOT THE RPM'S). MILE PER HOUR. On a ten speed transmission. (Model RT-910 Roadranger).
