You ain't kidding. My tranny's as picky as your's. It throughly HATES Honda MTL, and grinds on any fluid except MT-90 (which is almost unshiftable in the cold/morning starts). I'll give GMSFM a try to see if it can prevent grinds like the MT-90.

I trust Gernby's good judgement - the only "book" I have on SFM is that it has nothing in it that speaks to longevity in a high revving engine/tranny, while the RL's have the strength of their base stocks. That is not a real issue for me, as I change fluids every 2 years, which is 6k miles for me. I am going to try SFM based on Gernby's continued support of it.

But since I have not had any grinding with my 04's tranny, this is more of a scientific curiosity than a need for me. I dbl-clutch'd the first few 1-2 shifts on this car since day 1 (Honda MTF, then MTL), and then it shifts fine.

I will post my impressions, since "findings" have pretty well been covered in the VOA/UOA's.
