I will be getting an used si transmission very soon and I want to know what kind un fluid is best to use.

 

i am very happy with honda manual transmission fluid in my si transmission. i think the conclusion of the 30 page thread on the subject was something to the effect that all the manual trans fluids are essentially the same.

 

gm snycro takes away grinds like magic, also a cheeper alternative is penzoil syncromesh, its at autozone and ive have good results with it

 

You can contact someone with Rocket motorsports, Rocket has a magic blend of fluid that gets rid of grinds and makes shifting smoother. (www.m24x.com)

never knew that, any more info?

 

You can go to m24x.com or I think there are a few dealers on H-T including Rocket himself. I use the fluid and it's made a great difference, had a 1st to 2nd grind when shifting at high rpm's now its gone.

 

I use pennzoil syncromesh..No problems with it..

 

i used gm synchromesh. if i had known that pennzoil was about $10 cheaper a bottle and the same thing I would have gotten it instead. what are you going to do though you know. GM SYNCHROMESH or the PENNZOIL SYNCHROMESH are the best in my opinion.

 

10 W 30 works fine here.

I know the manual says to use that but is it alittle rougher shifting with 10w30 then wih mtf??

 

I use 10w30 too, it's fine. As long as you push the clutch all the way in, I don't see how you would have any problems shifting.

 

i think im the only idiot using royal purple tranny fluid.

 

No, your not.
