    Hello everyone ..I got a 07 volvo vnl670 with 13 speed eaton fuller..truck has million miles on it..my question is;
    When I up shift from 3 to 4 the rpm drops too fast and I can't shift it..4 to 5th gear is OK but as soon as I am on the gear I hit throttle truck kicks..5 to 6th gear same..by the time I hit upper gears the kicking is getting less...wondering if problem is with the engine or transmission or something easy to fix? Thank you

    Sounds to me like you are over revving your engine what rpms are you shifting at

    While I don't know your engine and tranny , the bottom side of any thing else I've ever driven 1st through 5th never liked going over 1300

    electrical glitch with the jakes??? Maybe????

    one notch kicking in. Not all 3.

    I don't see how an engine can drop faster cept when the jake is on.

    At a million miles, if that transmission has never been rebuilt, it's time. It will get hard on a 13 going into 3rd and 5th when they get tired.
