Grinding noise in neutral - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

What could this be? Sitting in my drive way in no gear itll make a grinding noise but when I push the clutch in itll go away, it also doesn't make the noise when I go as far as I can tell

That's the throw out bearing, it's normal. If you get a screeching sound get it replaced. Until then turn up the tunes.

google "neutral rollover."

Is it a serious problem? Because i have that noise too.
Is it self fixable or do i need to take it back to toyota?

If the transmission doesn't make any noise while driving then there's nothing wrong.

Idle up to about 2K RPM. I bet the noise goes away.

So far i only hear it when its idling/neutral. What is transmission sounds like?
I have a N1 exhaust...so i cant hear if the noise goes away or not....

I just try with my dad rev about 2000rpm,, the rattle noise still exist!

Very few mechanical things that go bad ...... fix themselves, including a bad TOB.

I'd suggest you pay a visit to your dealer and ask to listen to another FR-S for a comparison. While you are there, you may consider asking a tech for an opinion.

Most manual transmissions, when the clutch is NOT engaged, have a shaft(s) that rotate. This is a "transmission" sound, some call it a "rollover" sound.

It kinda sounds like a quiet clothes dryer, running on low speed, when it's empty.

It's probably a good idea to have a dealer tech give it a listen. A little neutral rumble is no biggie but who can say when it becomes excessive?

We're specifically discussing the sound of the transmission in neutral. this sound will disappear when you push in the clutch. If it doesn't disappear then it's not the transmission.
