Transport company hurts (7)
I believe the answer is:
coaches
'transport' is the definition.
(I've seen this before)
'company hurts' is the wordplay.
'company' becomes 'co' (abbreviation).
'hurts' becomes 'aches' ('ache' can be a synonym of 'hurt').
'co'+'aches'='COACHES'
(Other definitions for coaches that I've seen before include "Buses, carriages" , "Instructors in sports" , "Trainers for athletes or transport vehicles" , "Trainers or buses" , "cabins at the back" .)
