RE: First Manchester
The 2 and 1 buttons don't function quite as posted. In 2 it won't change into top gear and in 1 it won't change into either of the highest two gears. Earlier Voith selectors as fitted to Metrobuses and so also have a third button which prevents it from changing into top.

These features were no doubt removed to prevent drivers abusing them, just as the kickdown switch beneath the accelerator is also often no longer provided. High revs = more fuel consumption which is why the newer ZF gearboxes in Volvo B9s, Scania Omnicitys and so on are very quick to shift up a low engine speeds.
