Thank you very much Mark for all this expertise, both on FTE and the results, in our trannies.
Always look forward to your comments.

Fwiw, I don't see why it wouldn't work. If it keeps the valve open, so that the fluid keeps flowing through the cooler, the majority of the fluid will be exchanged.

'03-'07 we do not need to change the internal filter.
So I am curious should or can we "rinse" it out. It would seem at some point it would collect something, and eventually layer over with it.
Of course I am thinking with that internal filter screen having such "large" holes if it does catch a lot then there would be bigger issues?
Just curious not trying to cause trouble. :-)

I assume you are informing us that the 2008+ E-series are different? (I stand corrected on that - I just am not in the mode to think about the E-series).

Just read thru that and I did LIKE what I saw Mark Job well done!!
You did address some concerns I had in the writeup Like shifting of the gears and actuating the silinoids ect.... You Even made mention of using More trans fluid to make shure all the Old fluids are Expelled out what makes complete sense to me
Can you expand on why it wont work for out 5R110w??
I'm thinking that the Thermostat is part of the reason that procedure wont work on a Torqshift trans???
So in regaurds to the thermostat it did make mention of Blowing air into the Cooler lines to expel Old Fluid Out
What else would be a Concern with your write up if the procedure was used on a 5R110W
Its just like Big Inch mentioned these "Hot Flush machines" are hard to Find AND Probably even harder to find a Tech that would do it correctly
I'm just trying to Adopt a Trans fluid change procedure that would Expel the Most Old Fluid out and then just Increase the change interval some

My only concern is that it won't work due to the thermostat recirculating fluid instead of sending it out the cooler line.

Mark - do you know the mesh size for the internal filter? I know we (forum folks) say it is for boulders, but that is true only in comparison to the external filter that filters down into the micron size.

Mark,
Are we are overly obsessed with trans fluid changing..
If we drain and fill, then drain and fill again a couple weeks later, we have replaced about 75% (50%, then 50% of the remaining 50%).
If you tow "a lot" maybe do another drain/fill and you are good, with 87% fluid changed.
If you shorten the flush interval a bit that will help too.
I paid $140 for a "flush" when I bought it used at 98k but they only used 7 qts. So, i plan on doing drain and fills so i know what is being done.
I also have the "upgraded trans pan with the internal filter" ready to go in 1000 miles @130k
Thanks for all your expertise.

My only thought in regaurds to the thermostat is that it Leads to the Cooling line so if we use air to blow that line we can get a lot of the Old Fluid out in that Cooling Loop
Granted it wont be All the Old fluid in the Cooling Loop there will still be fluid sitting behind the Thermostat all the way to the Inline filter but the Majority of the Fluid from the Inline Filter threw the Cooler and return line back to Trans will be removed

Yes Im Obsessed LOL
But here is a Great Example^^^
You had a Flush Done and only got 7 qts of New fluid in it Aprox 1/3 of the old fluid changed
Well with Very little effort and some compressed air Blown into the lines when the inline filter is taken off I was able to get 12qts out and 12qts Fresh fluid in
SO Instead of 1/3 New Fluid I got 2/3 New fluid in it all at the Same time!!
I was shocked how much more fluid I got just with Blowing some air into the Line
