I have tried to research this, but finding conflicting info - and have a question I can find no answer for.
1) Some say it's not wise to flush with this many miles, as it risks dislodging bits that can be bad for the tranny. So just drop the pan replace the filter and replace the 4-5 quarts that come with the pan - then do the same again later, to work out the bits over time and replace more of the oil in the torque converter, since they quit putting a drain plug there with 2001 models.
2) Some suggest disconnecting near the cooler - start the engine a bit, until line sputters, then drop pan, replace filter, and seal it back up, and refill - and then run a bit more and make sure refilling until you get to all good fluid, then close it back up, run it a bit, go through the gears, then top off.
Current pan has no drain - replacing it with one with a drain plug. I thought I would run a quart or two of transmission flush through the system, then drain it, but without a drain plug, not sure how to really pull that off - which leads to the question I couldn't find an answer for.
3) With ATF being so pricey, I was wondering if I could drain the system (like in 2 above), drop the pan, clean the magnet, etc. put it back in place, and fill with the flush and 0w20 motor oil - just to use as a flush, just to be able to run most of the spent ATF out, run just a few miles on it, enough to go through the gears - with the flush fluid, then pull the pan, replace the filter and install the new pan (with drain plug). Then make sure all the motor oil is flushed out with the red ATF.
Just trying to do what's good to clear out as much old fluid, etc. out. In chemistry, it took three rinses to get contaminants low enough to not compromise what more would be done. That is in the back of my mind - and good 0w20 synthetic motor oil - to use as a part of the flush is far cheaper than ATF fluid, to use as a couple of flushes. Typing out loud aiming to be smart and practical about this. Thanks for any help the informed and wise in the forum about this have to offer.
