GMSFM --- Good Stuff
What makes this stuff better than any other transmission fluid? (I know that its "fiction modified - but I have NO idea what that means). I read Road Rage's review of it, and he liked it, but did not break it down like the Oil Journals.
Can anyone enlighten me as to why this fluid is so great?
Was this a joke? (Cant tell though type). Why would transmission fluid reduce noise (other than reduced friction of gears......), is gear noise THAT large of a component of road noise? Also, is that gas mileage expectation is for real? The official Honda EPA estimates are only 20 / 26. Depending on your driving, that expectation is almost DOUBLE the EPA estimates. I thought EPA standards were really hard to get, anyways, because of the conservative nature of the EPA tests.
If this is for real, someone please explain how it can extend gas mileage THAT much (if not that much...how much). If its for real, I will be changing tranny fluid this weekend!
Thanks in advance!

I no longer feel the need to add additional sound deadening material to the body. I am also expecting to see my gas mileage to improve to 45 mpg or so.

I have a question about this- I need to get my car inspected soon, and I was just going to schedule an oil change and tranny fluid change all in the same trip. Do most shops comply if I bring in my own tranny fluid and tell them that it what I would like it replaced with? Or will they give me crap and claim I need to use something else...also, although I'm sure this has been covered- how many quarts do I need for a full flush/change... Thanks!

Also, and I mean no insult by this, but if I distrusted the shop as badly as you seem to, based on your question, I'd be taking my car somewhere else!!
Good luck & Drive Safe,

PS: You'll need two quarts to change the tranny fluid. It won't quite take all of it, but it will be close.

I can't figure out a way to use smileys to convey straight faced deliveries of subtle jokes. Sorry.

When you reply to someone, or start your own thread, you'll find a box to the left of the entry field that you type your response into. It's labeled "Clickable Smilies." At the bottom of the box is says "Show All." You can click the mouse pointer on any of the smilies that are there, or the "Show All" link at the bottom which will bring up another box with all the smilies that are available on S2ki.
Clicking on the smilies will insert the appropriate characters that the S2ki programming interprets to create the smilie graphic. As an example, if you click the smilie face, it will insert a colon ":" followed immediately with a close parenthesis ")" and that will produce a
in the text when you post the reply. After you've done a few of these, you'll learn their shortcuts and can type them in directly. I find that faster, at least on the basic smilies, than shifting my hand to the mouse, moving it over to the appropriate icon and clicking it. Then again, I'm relatively comfortable on the keyboard. Non-typists may prefer to stick with the mouse. 
Drive Safe,

I thought it was a joke, but just wanted to confirm. I will wait another 10k or so until I replace (unless notchiness gets REALLY bad this winter). Had it changed 10k or so ago.What does the "friction modified" mean? I assume reduced friction, but how does it reduce it any more than a non-friction modified lubricant?
John
I haven't tried it yet, but I have heard from a couple of people that the smoothness only lasts 3000 miles or so then the notchiness comes back.. Please come back and post again after you've had it in for 5000 miles and let us know how it's holding up.
Thanks! Mike

^In my '02, GM Synchromesh FM (and also the AC Delco equivalent) has held up well. My car currently has 89k miles and I've been using GM Synchromesh FM since it had around 55k miles or so. I change it at 10k-15k intervals.
In my case, GM Synchromesh FM didn't completely eliminate the "grouchiness" of the cold transmission, but it did reduce it noticeably. You do feel some of the initial smoothness go away after a few thousand miles, but it seems to last longer than Honda MTF, and I personally prefer it over Honda MTF.
I've seen a bunch of varying reports, though, so your mileage may vary. Personally, I wouldn't switch fluids if you're happy with whatever you're using now. I only switched to GM Synchromesh FM because of my frequent 2nd gear grinds with Honda MTF.
