[B] I am not a mechanic but I am a car dealer for 18 years and have worked with 1 tanny shop for many years and the guy there is a pro on trannys. He told me never to flush a tranny due to the fact the old filter stays in and it stirs up a lot of gunk/metal shavings...I serviced my psd by removing pan and replacing the filter. Also my Ford dealership said the new flush is just a money making gimick...just my 2 cents

I would just drop the pan and change filter and aprox 5-7 quarts of the fluid that you will lose when pulling the pan...Again I am not a mechanic. Others may like the flush system. Good Luck

There are 2 seperate schools of thought on this subject. I will give you my personal stance and from what I have read, the stance of many elders on this website. I believe that flushing is almost always better than just leaving it alone. One reason is most tranny fluid starts to varnish at 240 degrees. These transmissions do not typically run that hot but with the history of these things I would want fresh fluid in there as often as possible. Many of the metal particles should be attached to the magnet. I have heard of filters being checked after 200,000 miles that look brand new. Next time you change the ATF I would pull the pan and wipe it clean. Clean off the magnet also. If you want to change the filter go ahead since its right there. If not I wouldn't worry about it. I would say that for now just leave it as they have it. You can take or leave this advice. There are tons of threads about this very subject with many different opinions. You just have to decide who you believe.

The guys at the shops I work for will not do a flush without removing the pan inspecting specifically looking for metal of any kind then changing filter gasket & refilling unit B-4 hooking up the flusher to flush the trans also B-4 the flush they test drive the vehicel to make sure there is not already a problem with the trans prior to service. flushing can most certinaly shorten the life of a trans thas has a problem. seen lots of folks that say ( Just had it flushed at the quick lube and now it's slipping) If you service a trans regurlary flushing is great but if you wait to say 75,000 mile your taking a serious risk..............

It may be a waste of money, but if I'm going to change the fluid I'm going to change the filter. If the fluid is in good condition, there are no issues with the transmission and you aren't changing fluid type (i.e., switching to synthetic) a flush is not necessary. Drain the converter and the pan, and you will get most of the fluid out. The nice part of a flush is, if done properly, it will give a complete fluid change.
