What is the common wisdom on an auto transmission fluid flush

This is an oft-discussed topic. Brown is bad, red it good. Good preventive maintenance happens more often than the manufacturer recommends. Remember that they only need the car to last beyond the warranty. A flush every 30,000 is often recommended here. Do a search for "tran*ny flu*sh" without the asterisks--red button, upper right corner.

Not everyone can flush your tanny, you'll need to search around for someone that has the machine.

Check out http://www.ezlube.com to find the one nearest you. Give them a call and see if that branch has a transmission flush machine. It wouldn't be a bad idea to drop the pan and change the filter, either, so ask them if they'll do that too.

Thanks for the info.

In fact, several people have replied that I should NOT flush a transmission for the first time at 126,000 miles because it may loosewn stuff that should not be loosened. The same analogy holds even more true for an older engine.

Perhaps I should simply have the pan dropped so that more transmission fluid gets replaced and replace the screen.

The dealer says I don't need to replace the screen on I30, '96.

Dealer also will probably say you should buy a new car when transmission requires replacement.

1) They are simply wrong. the best way to kill a transmission is to not flush it.There are 3 reasons this myth abounds:a)by the time many PPL think about it the car has such hi milage that it may go soon anyway f;lush or no flush.b) Others flush when the transmission starts acting up which in many cases is the sign of impending doom anyway.c) If you fail to combine a flush with the pan drop and screen replacement gunk flushed loose can indeed plug a screen ( reemember screen raplacement AFTER flush not before, almost all shops do pan drop and screen replacement first to save on new ATF.

2) With very dirty engine should indeed not be flushed ( at least not rigth away), as sludge can be broken loose and plug the oil filter pcikup screen (among other things).The best way to keep an engine clean are <frequent> oil changes a with good oils, An engine flush is still possible with a dirty engine <if you spend 6 mos to a year gently cleaning it nbit by bit w/ frequent oil changes and 45 min idling with .75 ATF quarts in it <just> before the oil change.

3) Nothing wrong with doung that but it should be after a flush for best results

4) Many dealers say that that doesnt make it any more correct, there is no such thing as alifetime filter/screen and "cleaning" it as some suggest makes no snese as teh filter isnt all that expensive.

Should be done right after running BG44K through tank, and before oil/filter change
