Lots of old school "truck enthusiast" type guys will refuse to give up their 13 and 18 speeds, but the majority of steering wheel holders could care less. I've driven a handful of different trucks with different transmissions. In local traffic, especially in an unfamiliar area, it is nice to focus on your directions and where your trailer is. But on the highway, I'd take a manual all day, especially in an area with hills. My first cruise through the West Virginia mountains with a heavy shotgun coil was white knuckle driving in an automated 10 speed that likes to upshift regardless of what you want it to do. Damn thing refused to hold a gear. I did however drive an automated 13 speed and that truck was a lot faster and smoother to shift and held gears the way it was supposed to.
All this said, more than 90% of new trucks are automated transmissions and companies like them because they are more fuel efficient and they aren't replacing clutches and gearboxes all the time because rookies aren't grinding gears and riding the clutch in them.
Where I worked asked the mill employees who wants a CDL, we need people to fill in the shipping department. Well I got lucky the school they sent us too, the guy running it was retired military, and he was cool, he refused to teach anyone to drive with an Autoshift transmission. So the frieghtshakers we learned in where 10spds, had about 20k in the van, and well they taught us everything the federal government makes you, and more.
Heck the guy running the place even helped this guy get his license, dude was in the school like 6 months prior and was going to take his final test the next day, but on the way home he got tboned and lost an arm. That instructor fought back and forth with the state until they relented and let the guy take his test, dude scored a perfect 100 while driving with a prosthetic arm.
Anyway long story short my work forked over like 40k to sent 10 of use the get a CDL class A just to drive an automatic yard dog that uses a 6.7L cummins and 6spd automatic. Waste of money, but I do have a license to fall back on.
Since working in the shipping department, yeah alot of folks are steering wheel holders. Alot of folks can't speak english worth a damn or hardly at all either, and some take forever to get backed to the docks.
Heck even some companies straight lie to there drivers when the send them to our place to pick up orders for delivery, they'll come in bobtailing walk into the office and tell us there here for such and such load and were like back up to dock 5 and well get you loaded. There like my dispatch said this would be drop and hook, well buddy they lied the only preloaded we do is for our own company drivers. Then they gotta go find a trailer from somewhere and eventually get back to us.
It's really a sh*t show when it comes to trucking driving is what I learned.
