The vast majority of class 2’s are manual 6 speed or auto boxes these days, but you do occasionally get the 8 speed manuals with range switch.
In my experience, those are usually the wrecked bits of kit, but saw less and less of them as my agency days went through. Likely because thry became too expensive to fix.
Do it in an auto and uou can quickly learn the pld style manual if needed.
As said anything 18 ton or less will either be a standard 6 speed manual box or auto usually apart from some trucks like skip wagons and anything above 18 ton will maybe have an 8 speed box but most newer trucks are all automated manual trucks these days.
I’ve done mostly Class 2 agency work since passing my test in February 2019. It’s been easily mostly automatic gearbox since. Done some 5-6 manual gearbox which is no different to a car or van. I did a week last year on a manual 4 over 4 gearbox which is a manual gear lever with a switch at the back. You have gears 1-4 as normal and then flick the switch to get 5-8. Takes a little getting used to as you can be in 6th and only doing 30mph. Went to Ireland this week and had it again but it all came back to me. Mind you, my first time was driving around central London so that was a fast learning curve. You’ll be fine I’m sure.
I quiet like the 4 over 4s after the first minute or two of ‘oh no not one of these again’ you soon get into it. I usually go 2/4 switch 5/6/8 occasionally start in 3 then switch and into 5. You soon remember to switch it at lights before you pull off. Once or twice trying to pull off in 6th and you soon get it.
So find the manuals easier to reverse , a some autos even with crawl mode tend to go from stopped to zoom quick, when reversing onto a dock it’s easier to kiss it rather than smack it with a manual.
