Dodgy adverts fish for items in transmission (5,6)

I believe the answer is:

drive shafts

'items in transmission' is the definition.
(as in a car transmission)

'dodgy adverts fish' is the wordplay.
'dodgy' indicates an anagram (a dodgy or wrong order of the letters).
'adverts'+'fish'='advertsfish'
'advertsfish' with letters rearranged gives 'DRIVE SHAFTS'.

'for' is the link.

(Another definition for drive shafts that I've seen is " they communicate power".)

I've seen this clue in The Times.
