Morphology
The meaning is directly and compositionally derived from 'transmission' (the gearbox that transfers engine torque) + 'shaft' (a long straight rod); together they denote the shaft associated with the transmission that transfers rotary motion. This noun–noun compound follows a regular compounding pattern and is conceptually transparent and cross-linguistically common, so a B1 learner who knows both constituents will readily infer its meaning.
Etymology
The compound noun transmission shaft comes from two simple words: transmission (something that 'sends power') and shaft ('a long metal rod'). Imagine a long spinning rod carrying the engine's push to the wheels — that's why it means 'a turning rod that sends power from the engine to the wheels'.
