Default To flush or not to flush?

ok folks Envy gonna have a full tune up done here very shrotly. shes got new plugs already and im gonna do the fuel ilter and belt while im at it. Ive done changed the oil and im gonna seafoam the crankcase and through the brake booster line before long. I got some amsoil 0-30 synethic going in after that.

So heres the question:
Should I flush out the tranny fluid or no? I hear a lot of people saying if it hasnt been kept up with dont do it now or it gonna get ruined. I can see as to how it can be ruined but if everythings that far gone already then I dont see why it would hurt to change it anyhow.

This is for my TA by the way

Well I dont know cuz we bought it wrecked. the tranny doesnt look all that old to be honest. when we got it, it hardely had any road grime on it. I mean it wasnt bling bling shiney but deff cleaner than the rest of the underside so that kinda leads me to beleive its not to old.

I was always told if it has higher mileage and you dont if its never been done before don't do it. It could loosen some of the gunk built up and lead to more problems. I'm not sure if mine has ever been changed in my 44k mile T/A and I am in the same boat as you.

LOL, when I hear the word flush, I think of how jiffy lube pushes new oil through to push the old out. What a joke! They dont even change the filter!

Do your self a favor and change your trans fluid and filter. I dont know where the hell anyone ever got the idea of " OMFG DONT FLUSH THE OLD OIL OUT IT WILL WRECK STUFF" idea from. What? is your old sludgie oil holding the trans together or something? lol.

just change it and feel good about getting all that corrosion eating away at your trans out. Also, take a look at how much **** that little magnet picks up in the trans pan.

well seni that actually is part of the argument which I can see happening. if the fluid ahsnt been changed it very well could be holding the clutches together.

I wonder how hard it is to change the filter

changing the filter is easy. I think this about not changing the fluid is nonsense.
Even if it was holding the clutches together,do you want them to be held together by old slugie oil? Does are cars come from the factory with clutches that are held together by old oil? If your clutches are held together by old oil I think theres a bigger problem that has nothing to do with the oil.

There are arguements on both sides, and I've heard theroies from knowledgeable sources support both arguements.....here's how some people see it.......

Old fluid will be more abrasive than the fresh slippery stuff. That abrasiveness might be helping older, worn clutches to grab. Flush it out, and a trans that might have gone a bit longer may now be toast sooner. This is why some people have found that putting Type-F fluid in a 4L60E that's starting to slip will buy you a little time. Type-F is more abrasive than DexIII, from what I've been told.

True, if the clutches are in poor condition you'll need a rebuild soon anyway, but a flush might speed the process.

PS. My own personal experiance with this topic:

I had a '94 Toyota years back. I didn't change the trans fluid till almost 80K miles. Right after that fluid change, the trans would slip a bit in first gear after a cold start only when very cold outside, but did fine once the fluid was up to operating temp. The trans did still last till about 120K before blowing up violently, but it always slipped a bit after that flush on cold days. And yes, the fluid level was fine.

IT has been proven time and time again. My mechanic refuses to change ATF fluid in autos. This is the reason why. It has a 50/50 chance at 80+K miles of raping a tranny that would easily go until 100+.

On a stock car, you should get 100K on average. Meaning, I've seen some go at 70K and some at 130K.
