Put out in unusual transport (7)
I believe the answer is:
rapture
'transport' is the definition.
('rapture' can be a synonym of 'transport')
'put out in unusual' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'in' means one lot of letters goes inside another.
'unusual' becomes 'rare' (I've seen this before).
'put' with letters rearranged gives 'ptu'.
'ptu' placed into 'rare' is 'RAPTURE'.
(Other definitions for rapture that I've seen before include "Intense joy" , "Exaltation" , "State of bliss and euphoria" , "Ecstasy, seventh heaven" , "Sheer bliss or ecstasy" .)
