Whining sound from (sr20,ca18) tranny

Are those products recommended for the OEM Roadster trans? Seems I read the Redline MT oil has a tendency to leak out, but I don't know about the shockproof additive.

I typically mix it with high quality GL4. Haven't had an issue.

With MTL if your seals are tired, yep it may ooze.

Funny, I have never had the Redline stuff leak.. But then I don't really use them that hard..

For the diff there is nothing better. Will literally save your rear!

Did you mean redline MT90?

Can you use it pure in the diff or mixed with other oil.
Which type schockproof is then the best to mix.

[JT68]

You can certainly use it pure. Would suggest lightweight, but not super lightweight. Heavier woud only be needed in extreme cases I think.

I usually mix with GL4 50/50 since it may help with weeping at the seals, but that may not be necessary, just depends. It is totally compatible.

The main bearing was damaged and I replaced it with a closed type.The gearbox is now quiet.
My diff makes stil noise, it whines a little. I replaced the oil in my diff with lightweight shockproof.
