Downshifting, how can I learn how to do it?

    OK well, I did better at least.

    The first small Nebraskian town I drove through was a dumpster fire. It was one of those deals where you have to make like 7 turns to stay on the highway.

    But those laid back Nebraskians didn't seem to care I clogged up their streets like a plastic toilet.

    Once out on the highway there wasn't a soul for miles, so that gave me ample opportunity to grind my transmission into submission.

    Next town, much better. Still jerks and grinding and such, but I didn't stall.

    Its frustrating, not to mention embarrassing. I just got all excited, jumped in the truck and took off to play cool flatbedder.

    I got it downshifting pretty easily in the higher gears. Right at about 6th or 7th it's still stubborn.

    I'm not muscling the shifter, I'm keeping it gentle. But that grind and that jerk during an awkward shift, that's not gonna hurt the truck, is it?

    @TravR1 the shifting will come back to ya it just takes some time. The truck you’re in might be finicky too. I’m convinced a guy could get in one truck and then the one right after it off the assembly line and both would shift different. I don’t wanna derail your thread here but as a sidebar weren’t you running plasma or something with FFE?

    I did 3 years with FFE! Their plasma is a team deal. Eventually decided I wanted my own truck.

    Despite my difficulties, flatbed is fun so far. I drove all the way to the consignee and there's a big, wide open lot for me to park in. No parking woes.

    I'll probably do this for a good while if I can keep out of trouble. There's more to worry about. More stuff DOT can jump on you for.

    That load is only like 35k or something like that. But I also forgot to ask how to scale those spread axles before I left. Lol

    When I drove stick. And its been about 3 years. Before I would come out of the gear I was in I would tap the brake so I was at the bottom speed for that gear.
    I would gently push the throttle and nock it into netrual. Putting me in the midrange speed for the gear under it.
    Once in neutral I would hold the shifter in front of the gear I wanted. And when the speed and rpm matched it would suck it right in.
    Took about 2 months to master, at first I was slowly down to much. And ended up switching from 9th to 7th. Instead of 9 to 8th. Which helped on the hills, but killed my ego on the flats.

    You're just a human trying to tear up an Eaton. Good luck. The real problem is when you get it partially in gear, and put the beans to it. Then it pops out of gear under load, and breaks the corners of the gears off more and more, until it won't stay in gear on it's own anymore. As long as you're always fully in gear, you can really abuse the crap out of it.

    It's been more or less answered, but for downshift RPM split - when you're in ninth, and shift to tenth, note your RPM before and after. That amount of RPM lost when you got into tenth will be the same amount you have to "give back" to get back into ninth. And it will be like that for every gear. (not the same amount of RPM, but the same method of figuring it out)

    Little off topic but, was it a easy transition to change divisions from Shaffer to Hunt?

    I usually gave the clutch a quick tap when that happens and it falls right in.

    You just ask to move over and it happens. You have to still do their orientation and 3 days of securement training.

    Not quite as easy as moving between Crete and Shaffer, but not bad.

    Better today! I worked on "feathering it" and it will slide in. Staying calm makes a big difference too. Who woulda thunk?

    It helps that I'm sitting in the truck by myself and there's no one watching.

    The lower gears are harder to downshift than the higher. But I can get it down to like 6th or 7th gear and the truck will go as slow as I want. Then I can just stop and reset it.

    Its coming along nicely. I'm glad I have the chance to learn before all the shifters are gone.

    My truck is older, maybe a 2016. My guess is it won't be in circulation for too much longer. Then who knows.

    This fleet only has a "handful" of autos. So maybe I'll be in shifters for a while.
