If I change my transmission fluid by replacing 3.5 quarts at a time, how long until all the fluid is new?

It holds 8 quarts total. With my car I can remove the transmission drain plug to drain 3.5 quarts easily. The torque converter holds lots of fluid though.If I change my transmission fluid by replacing 3.5 quarts at a time, how long until all the fluid is new?
Theoretically it would never happen, but there is a way to get most of it changed. It involves changing the fluid in the pan, and once this is done, disconnect the fluid cooler line going to the radiator. Attach a piece of tubing to it and put the end in a suitable catch container. With the engine running and the transmission in drive, catch the fluid as it is pumped out of the transmission, and at the same time pour fluid into the transmission fill tube, until the fluid coming from the tube is clear and new looking. Read about the procedure at: http://www.allpar.com/eek/atf.html (About the center of the page) Don't forget any of the safety procedures. I used the procedure on a 1981 Ford F100 and it worked great. ...Good Luck..If I change my transmission fluid by replacing 3.5 quarts at a time, how long until all the fluid is new?
You'll never actually replace all the fluid this way. Imagine changing 1/3 of your oil at a time. There will always be some residual old fluid. Don't forget that most automatic transmissions also have a filter that needs replacing,too.If I change my transmission fluid by replacing 3.5 quarts at a time, how long until all the fluid is new?
it will never get new cause you'll be contaminating the new fluid with the old each time so if there's any particles there which is usually the case they're gonna stay there even if you drain the tranny the torque converter still has fluid in it son go to a shop and let them do a flush its the only way that fast and safe to change your transmission fluid
