Default flashing for ATF oil

I had drain my ATF oil for the third time and still the oil dirty
Is there a procedure for flushing the A/T rather than draining the ATF oil and replace it with new one
Thanks

Here is a simple non-detailed procedure.

Just undo the line to the oil cooler at bottom of the radiator. Then start the car for about 20-30 seconds at a time and watch for the tranny to pump out the tranny fluid each time you start it.

Fill the tranny back up with eight to ten quarts and you're good to go. Make sure the level is correct.

It is cooler line on driver side of radiator. I would suggest you start car for about 5 seconds. That should give you 3 quarts. Measure what came out and refill with new fluid through dipstick hole. Do this repeatedly until you see cherry red new fluid coming out, then refill and top off. When top off, leave car running until reaches OPERATING TEMP then top off.

Or, you can take off both lines and insert the inlet line in a new jug of ATF and the outlet into a bucket.

Run the car till the fluid runs clear or you run out - if you run out then swap the jug for a new one.
