I was told by many that a Full Transmission flush would be a very bad idea!
I've been wanting to get my transmission flushed for about 3 months now... (have been delaying b/c no time to do it myself) today i went to ask around for prices and i was told i shouldnt (and THEY wouldnt) do a full flush since i didnt know when it was last serviced (brought the car used w/ 108k miles Jan 1.) They said that a flush is recommended only if it was maintained every 30k miles since the car was purchased new..) I have been told this by 4, pretty qualified, people: The Dealer, Cottman transmission manager, damn good mechanic i know, and a firestone serviceman. They said that i should only do a Drain and refill.
ALSO, for the drain an refill, cottman said a synthetic would be good, while damn good mechanic said the opposite. im so confused!
can someone help?!?! ALL I WANT TO DO IS A COMPLETE FLUSH WITH MOBIL1 AFT! BUT NEED SOME MORE ADVICE!

Man i hope you guys are right, i just dont want to mess up my tranny... is there anyway i can tell whether or not to do the flush by looking at the magnets and screen after i drop the pan? for example if magnet and screen look pretty clean, would that mean a flush would be ok? you guys are making me feel better about doing the flush, but im still not 100% sure.

Small metal debris and particules floating in the ATF increases friction between bands, and helps reducing transmission slippage. This is why there have been some reports where a full flush with new ATF caused some auto trans to start slipping after that.

okay since no one got this I'll take a stab at it.
Example:My motor has 236K on it. Why wouldn't I switch to synthetic? My engine has had 10-30W for as long as I've owned it. I'm sure the previous owner didn't put in synth. So what happens if the next oil change I use synt? My motor will start to hemmorrage oil. I will probably get multipule oil leaks. Why? The 10-30 isn't man made. It has varying particle sizes (bigger pieces of oil parts).
The same applies to the trany. You could put yourself in a world of hurt.
