Replacing the filter first is really the way to do it. Unfortunately, what I've observed is that the lazy SOBs use the machine when they DON'T want to go to the trouble of dropping the pan and replacing the filter.
Whichever way you go, make sure you understand what you're paying for before the work is done. Then, make sure it really did get done the way you wanted! The theory's all good, but in general, the only guys I've ever heard recommend the use of the flushing machines were guys that had to make payments on a brand new flushing machine. YMMV.

You do want to make sure they're still changing the filter. They USED to do it at the quick lube around here as part of the service, but now it's a Jiffy-lube and they don't want to get "internal", though for an extra $60 or something they will usually do it. If I recall correctly the way they described it (which seemed ot make sense) was that they replaced the filter, and then flushed and only the clean oil from the machine was going through the filter until the flush was completed. I guess I'm assuming if that is correct that one of the oil cooler lines goes more or less directly into the filter before continuing on into the tranny?... Levi
