    wow. dont listen to justin.

    cummins 5.9 diesel "stock" is going to run around 5 to 10 psi for your fuel pressure.

    most run around 6 to 7psi. ive seen many drop down to 2 or less under a lead foot ( or heavy load ).

    as long as your gauge says 5 to 10 psi. your fine. your safe.

    now if your diesel is modified or more than stock. 12psi is the way to go. let her drink better.

    my opinion. no more no less.

    your tranny.

    200degrees is the max you ever want to see. you dont even want to run it that hot for a long period of time.

    knocking off 20 degrees will almost double the life out of your tranny. look on line for a auxiliary oil cooler. your tranny will love it. and so will you

    it depends on if its a gas powered or diesel powered

    if its a gas powered between 100 and 150

    diesel is 80-120

    and normal temp for a transmission is 90-95 degrees Farenheit

    or 50-60 degrees Celsius
