6SP gear oil?

[kiyanichenko]

Hey, im fairly new to the Nissan scene, but Ive been searching a little on the spec-r 6sp and didn't find much. I want to change my gear oil and don't know what to go with. It has about 60k on it and grinds into 2nd gear. I was wondering if I should use a synchromesh, standard or synthetic oil, and so on.
Sorry if this is a "use the search button" post. I couldn't find information on it.

Thanks

i heard the syncromesh is good and also amsoil is also good.

The S15 6speed is the same as all other Nissan trannies... search 'tranny oil' or similar to see what people think. I'm a fan of Neo synthetic, but have used the cheap Valvoline stuff as well - it's a little better. Redline is generally not seen as a good choice for these trannies. Take a look around, we have tons of fairly recent info available.

AMSOIL 75-90W GL-4 Manual Transmission fluid...3 qts of it and be done.

Be sure the trans oil doesn't attack yellow metals... Get the oil Flip has recommended, I run it in my Z32 trans.

Thanks flip. does it have synchromesh mixed into or something like that?

[jr_ss]

No, it's just a BA oil to use in the trans... Many people are running it without problems..

Amsoil is what I am running in my 6sp trans and love it! I am also a dealer and can give you a good price on some!

Any GL-4 oil will not eat synchros...STAY THE FUCK AWAY FROM GL-5 oils...
