Transmission Flush, panacea or poison?

[Diogenes]

Good thread guys! I just had my tranny flushed and had them drop the pan to inspect for metal..

Question I should ask.. Isn't it generally expected to find very fine particles of metal in the bottom of the pan due to normal wear and tear?

I'm still questioning the credibility of the shop that did my service, since I'm new to the Boise area. The mechanic claims that the amount of metal flakes I had in my pan was excessive. But then again, he had also told me that the ATF levels were good before he dropped the pan and that the fluid looked good. The residue he showed me after dropping the pan was pretty damn black. So I'm wondering if he showed me particles from someone else's transmission.. ;0) I wasn't present for the inspection. However, had the Tranny refilled about 4K miles ago and there were no signs of metal.

My gut tells me they were far too ready to get me to invest in a complete rebuild, even though I'm not detecting any physical signs of slippage. And given the amounts of money involved, as well as proclivity for false sensor readings, I'm a bit dubious of many transmission mechanics recommending repairs that are not necessary.

I'm still under the belief that I was generating a false positive on my P1870 code. So I'm wondering how quickly that code will pop up again after the flush/replacement.

Still trying to find out if transmissions from Troopers or Rodeos/passports are interchangeable with VXs..

Yes, my 4l30E came out of a Trooper. If you are going to spend the money, you should get the 4l60E, direct bolt in, and a much stronger tranny. Wish the insurance company would have okayed that for me, they said they wouldn't pay a dime if I did, even if I offered to pay the difference. Now that company went tits up, and I am waiting on the court date for the lawsuit. BOOOOOOOO!!!

If you aren't getting slippage, I would do nothing, what is the worst that could happen, you have to get the tranny rebuilt? I paid 900ish for mine, shipped, with a 3 year warranty.
