if he f'ed-up the downshift you are most likely into an overrev situation. get your mechanic to put a pst2/piwis/duramteric on it an look for recent overrevs. don't know the year of your car, but if older than 2002 then the 'type 2' overrevs are the bad ones. if any recent time in that zone then pull the oil filter, check for metal debris, and go from there.
