Looks for specials at your area shops and see if you can find an inexpensive flush.
You dissconect the line leaving the cooler, going to the trans. Connect a temp line to the cooler and have it run into an empty bucket. while the engine is running in neutral add new fluid while the old is being pumped out. Keep doing this until you see new fluid coming out. Make sure you always have a constant supply of fluid in the trans. You don't want the pump to suck air. This method works fine and will flush you trans and cooler. No it will not get all the all fluid out. There will be fluid trapped in the valve body passage ways and the pistons, but it will remove as much fluid as the machine.

It won't remove as much as the machine. The machine puts fluid back in through the cooler return line. Doing it the cheap/free/bucket way does not flush anything from the cooler back to wherever the dipstick/fill tube pours in. I don't know how it is all piped but it does leave plenty to be desired.

Now with that said, this is how I did my last transmission flush too. It's free but less than ideal.

Got ya.... well I forgot that my GF's father knows a mechanic with his own shop and he comes pretty well recommended so I gave him a call and he's going to do a full 10.5quart (I think that's the number he said) tranny flush on my car with the machine, as well as replace the spark plugs (cost factored into my total cost), and all of the spark plug wires (cost factored into my total cost), do a tire rotation, and lube up everything under the body.... for only $250 cash. When I called the stealership the other day they wanted $220 just for the tranny flush alone!
