I have plowed snow for 35+ years. My first trucks were manual. They were terrible for plowing as in the act of shifting, the tires would break traction, even if you were skilled with a clutch. A possible disaster on an ice covered hill. Just one more thing to do on a narrow ice covered driveway that automatics do flawlessly, leaving the hands free for the plow & steering wheel.
I have no trouble realizing my tires are losing traction with an auto. The engine revs, the tach jumps up the truck slows down. Any or all of those conditions.
I have automatics now and have less problems getting stuck or losing control and can focus more on what I am trying to do-especially when plowing. If I want to hold a gear, like a manual, with a push of a button, I can hold, upshift or downshift with no clutch.
Now if i were a long distance trucker, I’d want a manual because they get better fuel economy. But automatics are catching up in that, too.
I can destroy a manual transmission dump truck in a race while driving an auto, but I don’t race dump trucks much lol
