A two-sticker can be a hand-full if you've never been schooled in floating the gears.

I learned from an old-timer that the clutch was only used for stopping and starting. All shifts, according to him, were done by 'floating' the gears and matching engine speed/transmission speed/road speed. I quickly understood you need to 'hear' the right rpm for the gear change.

Upshifting - Main up/brownie down was done main box first.

Downshifting - Brownie up/main down was done brownie first.

The reason for that was the first shift was easy, since the engine speed would be low. The second shift of the appropriate box was done by getting the stick into N, revving up to the right rpm, then easing it in. Don't shove it into gear, try to feel the gears engaging while you gently put it into gear.

And, if you're driving an old B-series Mack, it is okay to reach through the steering wheel to shift the aux box.

Anyway, just my 0.02 USD worth.
