Cricket team volunteers first to get transport (4)
I believe the answer is:
taxi
'transport' is the definition.
(taxi is a kind of transport)
'cricket team volunteers first' is the wordplay.
'cricket team' becomes 'XI' (a cricket team, from Roman numerals for 11).
'volunteers' becomes 'TA' (abbreviation for Territorial Army).
'first' is a charade indicator (letters next to each other).
'xi' put after 'ta' is 'TAXI'.
'to get' is the link.
(Other definitions for taxi that I've seen before include "(Of a plane) move slowly on the ground" , "Motor-cab" , "Public service vehicle" , "run along the ground" , "Motor vehicle for hire with driver" .)
