What do you use in your Honda LSD transmission? Why?

I was thinking going to the Amsoil MT Syncromesh Fluid.

 

Honda MTF. No explanation required.

 

Ummmm OK ....

I am asking for one.

Why use Honda?

Is it THAT good that there is no substitute?

 

There are substitutes, but I just know that the Honda MTF works as good as any.

 

Honda mtf fluid is not like most gear oils people use. I remember buying gear oil for a vr6 jetta, and that stuff was 75w90, if you put that stuff in your honda transmission, it will not like you at all, infact, it may not shift at all.

Reason for that is you can run 5w30 non sythetic engine oil in your transmission, dont believe me? RTFM, it clearly states you can use engine oil. Therefore the viscosity is different. Regardless whether its LSD or not, the synchronizers stay the same and if you use something of higher viscosity, i can guarantee you, you will have problems shifting.

Now there is the GM synchromesh fluid which is rather the same thing just has few more better additives which help with smoother shifting, less grinding and supposedly provides longer lasting protection. So really just need to look at the viscosity and make sure its nothing crazy high.

 

i use GM syncromesh in my YS1. love it.

 

For the last 15 years I have been using a good 5w30 engine oil. This is my first LSD tranny so I was just poking around to see if there was anything I should look for due to to the LSD unit as an option.

Thanks for the great info.

I will be going with the Amsoil since it states it will work in Honda MT's.

I will post how it feels shifting compared to what I had before.
