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.

I think it may depend.... If you know the trans is giving you trouble, and you have it flushed, and all of the sudden it fails.... It wasn't the flush that caused the failure, this trans may have failed down the road and all you did was speed it up...

If you flushed your trans and the fluid was black and bruned to a crisp... Your looking for impending doom no matter what you do..

If you are flushing to get the metal bits out of the trans, you may have bought a little time... Not too much tho... Just ask Wren...lol

If you have kept the fluid changed, and you know it was taken care of, I'd say you should be ok with a flush..

If you don't know if the trans has been serviced, take a good look at the trans pan... Mo service places paint the bolts to make sure it has not been tampered with during the warranty period, this would be an indication that the fluid has been changed before.. Several coats of pain on the pan / bolts means it had been done several times over at a shop..

Other than that I still reccomend dropping the pan once a year

Lash have you changed your fluid?

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.

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

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.

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>

I will have to sneak under there and drain and replace the fluid while you aren't looking... lol

You too are in FL, and you know how hot it gets here.. I call that Severe Duty
