I could never justify that purchase for non-commercial use.

One option is to just drop the pan and change the  filter.  Add a 
drain plug if not equipped.  You certainly leave a lot of old fluid 
this way, but now draining and refilling is easy.  You can do that 
more often, without filter changes every time, and even with the old 
fluid left behind, the "average" fluid will stay pretty fresh.

Another alternative is a "do it yourself" type flush.  Keep in mind 
that running the transmission dry is a very bad thing, so you have to 
be very careful if you try anything like this.  Here are some 
instructions I read, specifically geared to a Chevy Suburban:


Have +16 quarts of tranny fluid on hand. 5/16" dia hose about 4 feet 
long. 5 gallon plastic paint bucket (empty) with lid. Tranny fluid 
funnel (long, thin with smaller dia end to fit into tranny dip stick 
tube). Pan gasket, filter. Helper.


Disconnect the line from the tranny to the radiator. I'm considering 
making a fitting to connect to the return line connection at the 
radiator (later). Connect the 5/16" dia hose to the line from the 
tranny and snake it away from serpentine belt and into the 5 gallon 
catch bucket.

Take out tranny dip stick and replace with funnel. Have several 
tranny fluid bottle opened and ready to pour.

Start engine and the fluid will flow out of the line into the catch 
bucket. You have 5 quarts worth to work with before the tranny pan 
goes dry. Turn off engine.

Do the standard pan drop and filter replacement. The pan should be 
empty or nearly empty. Button up.

Pour new fluid into the funnel. Gravity feed, so it will come out 
faster than you can pour, so watch the amount and shut off the engine 
to catch up. Restart and cycle this through a few times.

When all 16 quarts are gone, you've just done a transfusion flush and 
got about 90%-95% of the old fluid out.

Reconnect all and you are done. Log into in your records.

Recycle center will take the old tranny fluid.
