Yeah, Ive seen alot of Amsoil gearbox conversations on some online forums too...I find most forums boils down to Honda MTF, Red Line MTL and the GM synchromesh and sometimes like I mentioned, even Amsoil...
It's just really confusing, because Ill get the odd comment here and there about Red Line being the worse thing you can put into a N/A Integra tranny with spirited driving only (no race or drag) and I'll see another comment about Red Line being the best thing to ever happen to Honda transmissions.
Alot of them are saying Honda MTF thats it thats all, don't put anything else in there...
I just find it real hard to pick and choose which gearbox oil to go with, so many confusing comments everywheres, it's unreal.
