In summary, two schools of thought:
- Change it regularly. If a problem does appear post fluid change, it was probably something that was going to occur anyway. A lot of people claim that a failure was caused by the fluid flush, but fail to mention that the reason they were changing the fluid in the first place was because they were experience issues.
- Don't touch it at all. If your transmission is shifting fine, leave it alone. This is line of reasoning is usually adopted by people who believe that flushing transmissions causes issues.
So, you decide which kool-aid you want to drink:
Preventative Maintenance is Best VS If it Ain't broke, Don't Fix it
My thoughts are,
If you are having no issues but can afford a new transmission tomorrow if things go bad, I'd flush it and hopefully it gets you many more trouble free motoring.
If you're having no issues but can't afford a new transmission tomorrow, I'd just leave it alone.
If you're having issues and can't afford a new transmission - flush it and hope it rectifies the issues.
If you're having issues and can afford a new transmission, decide whether you can afford to throw money at a possible fix (ie flush) vs a certain fix (reco'd trans).
I think that's a more rational approach than a bunch of anecdotal evidence!

I see where you are coming from. Its just on the forums and outside its really hit and miss and I wanted to get a head count of people on here who did do it at a higher mileage with no problems or did have issues. I trust the shop that did mine as he's been in the business for years and he technically could have screwed me and made even more money on me by doing the drain, etc but didn't.
Reason I wanted to do it in the first place is at cold starts not warming it up for a few minutes and driving it I would get the slam into 2nd gear. Ive read that can be due to dirty filter or low on fluids. Only happens on cold starts when warm everything is fine! That's why I was looking into this. If not I would have just left it alone. As stated if Ive owned this earlier with lower miles I would have maintained it.
