OK I did transmission fluid flush on my 02 4.4i

[jsoto]

Just wanted to add this to the wikipedia.
For me, ZF5HP24.
3 Bolt Drains/Refill.
1 Pan Drop, NO Filter Change.
Fluid was cheap for me.
No issues up to this point.
Note, I have been experiencing the 2/1 downshift when I approached 98K miles, but this happened more/noticeable when I was on a incline and in stop and go traffic bumper 2 bumper rush hour traffic.

Full Pan Drop, filter, line flushed - I think I used about 11.25 qts .
The 2-1 downshift magically went away !
2500 miles later, G1 started slipping on me. 2 minor times with a hard bang into gear, then later in the day, straight slip until it hit 2nd gear with a hard bang and then limp mode, 1 stop sign away from home.

I did not hesitate going with the rebuild..
She's running strong. I'm still putting it through it's paces but sofar, sogood.
