I was just wondering if this was OK to use in my transmission. It is BG Syncro Shift II Synthetic Gear Lubricant SAE 75w-80. API GL-4.

 

haven't heard of that fluid for a few years, that used to be a much sought after fluid for Honda transmissions in the old days. Is it really a 75w-80 ? , that might be a tad thick for the tranny, it might work in a hot climate such as yours though, I wouldn't want to use it in a cold climate. That is a high quality manual tranny fluid though. If you aren't getting good performance out of Honda MTF it might be worth trying to see if a thicker fluid helps your tranny, my first choice is always Honda MTF on a properly working tranny.

 

My tranny is properly working. I just had a few quarts of this lying around. I figured I could save a few bucks by using it instead of having to shell out money for Honda MTF. Providing it's ok to use in out tranny that is.

 

Honda MTF is cheap.

And it works the best out of anything.

Honda Green Label....

 

A lot of Evo guys swear by BG Syncroshift. Haven't heard of too many folks using it in the S though.

It is indeed a good fluid, but why not stick with Honda MTF? As others have said, it's cheap, it works well, and you generally can't go wrong with OEM.
