Ive heard horror stories about transmission flushes, but not dropping the pan. I would just skip the flush altogether.

Typically the stories you hear are when someone flushes as a last resort to a known transmission issue. The flush doesn't usually help at that point because all the material in the fluid is the only thing causing friction for the transmission to continue working.

It seems that everyone has heard the stroies, but they are almost always second hand. I also think they are passed on by quick lube places as sort of a disclaimer, so that people won't come and blame them if they experience transmission failure after a recent flush.

I believe that willwren even challenged anyone to give him a real live example (with proof) of this trans flush failure and, as far as I know, that has never been done.

Bottom line, stories don't mean crap, proof and pictures do.

Mine has been flushed two times in it'* life and is probably due to drop the pan and change the filter. Thanks for pointing that out ya' $#%&#@@*. J/K

Each time it was flushed, I was told the potential failure after flush story, thus I developed my beliefs.

I'm proof, it'* happened to me twice. Tranny was slowly developing problems, got a flush, then it let go soon afterwards both times (yes, I do flush once a year since the first rebuild). A few weeks before my first failure, I flushed it for the first time. It failed the second time 4 days after the 4th flush since the 1st rebuild.

Both times, I believe I/they flushed out the muck that was holding things together.

And we wonder why your trans is as good as mine after all of those miles..

I always hated my fluid being anything other than red
Well, I have had a tendency to let it go longer than I should, 'cause it'* just such a messy job (I know - wah, wah - lol). But truth be told, I had it flushed each time it started to turn from red, at about 55K on each change. I guess that I've been pretty lucky so far with my trans. <knocks on wood>
