    Re: v8 rpm jumps

    If you're coasting, your transmission may still change gears changing the RPMs of the engine...

    Re: v8 rpm jumps

    The ECM may be anticipating a downshift to maintain speed control and increasing RPMs for smoother transition, but the TCM doesn't cooperate. Mine does this, nothing to worry about.
