'part of the driving' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?

'mechanism brings rage?' is the wordplay.
'mechanism' becomes 'gear' (gear mechanism is a kind of mechanism).
'brings rage?' becomes 'shift' (I can't justify this - if you can you should give a lot more credence to this answer).
'gear'+'shift'='GEARSHIFT'
