Synchromesh vs. Synchromesh FM
Hey everyone, I have a 07 Tl-S 6Mt and I am looking to swap the MTF due to 3rd gear catching a bit. What fluid should I use? GM SM or the SMFM? Friction modified stuff is hard to locate in Canada (SK). What is the difference between the two?

Hey Nathan, as justnspace said, the MTF is now branded as ACDelco Synchromesh Friction Modified both in the U.S. as well as in Canada. As for which to use, there is a dramatic difference between the two, using the non-modified stuff will be of zero benefit to you, if you want that third-gear catch to be fixed, you must use the Friction Modified version.

You use the friction modified stuff as well? How do you like it? I found some today at the last dealership in town (had to try 3 dealerships and 5 parts stores) for 37 dollars a bottle :/ I guess I have to pay the premium, everyone says it works wonders.

Yes, using the SMFM stuff. I got it put in several years ago I think around 88k miles. And just got it replaced again at 168k miles. I do not have the 3rd gear issues....but I had odd 2nd and 6th issues which have gone away since switching. With the fresh fluid, it really is smooth as butter again.
And for what it's worth, NTB paid $14 per quart from our local Chevy dealer and charged me a total of $90 for the swap. I was there in person to confirm the they were using the correct fluid as well.
