Great video, flawed reasoning. You'll never get fully clean fluid that way. Maybe pretty clean, maybe not. My question is how well would 1/2 old and 1/2 new fluid perform? Would the new degrade into old fluid faster since it started out all mixed up with dirty fluid?
The problem is people oversimplify this 2 quart at a time process. Lets assume the fluid can actually be a "percent clean". After you do it a few times, you're removing and throwing away a lot of "clean" fluid, since the fluid you're removing contains a large portion of fluid that you added last month, or the month before. The farther along you get in the process, the less and less dirty fluid you remove. I made a spreadsheet that includes "clean" fluid getting removed with the old, and if you don't include pan drops / filter changes, after 10 "suck out and replace" intervals (20 quarts of fluid) you end up with 78% "new" fluid.
So, you just bought as much transmission fluid as I did when I flushed mine AND then dropped the pan and changed the filter, but you only ended up with 78% clean fluid...if that is even possible. Personally I consider it still dirty if it was being mixed up over the course of 30k miles. There was dirty to start, and more was created through wear.
I bought 22 quarts of the fluid I wanted, a filter, and then I had my shop do a flush using my fluid. They charged me 50 bucks. Then I dropped the pan, wasting 6 quarts of the newly flushed fluid, and change the filter. Finally I refilled and was done, and it was 100% clean, new, and I didn't have to jack with it again for 2 years.
