Should I be concerned?
Figure a fluid exchange probably pays an hour at ~$100/hr, ~$5/qt for Motorcraft Mercon V ATF, ~$35 for a trans filter and whatever the shop rate is for a pan drop and filter change.
Personally, I like to do the pan drop and filter change myself then have a shop do a fluid exchange. After that you have a clean trans filter with no old fluid in the cooler, radiator, TC, or anything.
Anyway give em a call & see whats included at that price. Around here, unless we ask & pay for a pan drop & filter change, it isn't done.
It's too late now for you to do now, maybe next time, but it's really easy to do this service at home ourselves, if we like turning wrenches & don't mind a little tranny fluid on our hands.
You should be able to do a filter change & full tranny fluid pump out at home, for at least half their price.
Here is how I do it on my 99 Rangers 5R55E & the 94 Taurus AXODE trannies, yours will likely be similar, maybe slightly different locations for the auxiliary cooler hose locations, pump volume with time & pan capacity, but otherwise it's the same overall idea.
