    The BACK of the transmission is driven by the tires.

    The FRONT of the transmission is driven by the engine.

    Since the gears are not syncronized, you RIGHT foot and CLUTCH are the Syncros'

    Shift into nuteral, let the clutch up, rev the engine till the gears mesh, and slip it into gear.
    Main is about 900 RPM's. Aux. is about 300 RPM's, plus or minus any speed you loose or gain.

    That's the down and dirty - - - now go practice for a while.

    Practice is what it takes to shift smoothly.

    A few trips around the town and things will get better - - - the more you drive it - - - the better you'll get!!!!

    Another way of thinking about it:

    The engine needs to be at the same RPM as it would be at if you were already in the gear you're trying to shift into. Once that is achieved, the transmission will slide into gear effortlessly without even using the clutch.

    It helps by watching the tach, but that ends up being a distraction...

    Once you figure out how to 'listen' to the truck, you'll get it.

    loaded or empty will make a difference, uphill or downhill matters, if spectator is with you makes really huge difference

    so you only press clutch to take gear lever into neutral, then rev and hold gear lever into position, then when the engine and gearbox are at same speed the gear will engage.
    so you dont clutch again to engage gear but rev engine.
