transmission fluid with less whine?
Hi people,
I've been running on motul gear 300 on my transmission since last september. Driven around 10000 km (or 60k miles) with the new fluid. The car shifts fine, and it's been through sub -30 C too. But sometimes I wish it was a little bit less whinny. I know it's well normal for the car, but I was wondering if there is any other fluid that's a little bit quieter. The whine is not loud at all, and I can only hear it when it's under load in 1st, 2nd, 3rd, and 4th (it should whine in 6th, but I never notice it), as it should be that way. I just remember seeing a post somewhere on the forum mentioning that the factory fluid is thicker and a new fluid might whine a bit more... I might be completely wrong on this regard. With that said, I can't remember what it was like with the factory fluid since I was new to the car and replaced the fluid only after a few weeks I bought the car. Thank you. |

I guess I was wondering if someone has tried a few different fluids including the Motul one and others. As of now, everything works fine as is, but when the time comes, I might consider the OEM fluid or any other popular brands. |

If he replies, keep in mind, it's over 105 degrees F down there and he just may be in one of his cranky moods - As far as my 2013 FRS MT, it has the same fluid in it that came with the car. My transmission makes no noise at all - of course, I don't hear too good anymore - |

The whine's not from fluid. It's because the transmission took a whack or many. Probably the input shaft bearing. I've told my story a few times here. Was dіcking around with mine and started some wheel hop. Immediately noticed a bit of the telltale whine. Pulled it a few weeks later to prep it for repair, and installed another salvage transmission. Immediately was WAY worse. I said "Fuck it. Let's see how it holds up." That was like five years ago. No change at all. One of these days I'll get around to swapping them again and inspecting the beater transmission.
Unless it's really awful, I wouldn't sweat it. Just be careful about abusing it. They're pretty fragile.

Sure thing! It's not normal except it is, sort of... I'll make a thread about it when I finally get around to doing the work. I have some ideas about what might be causing it but it's all BS until I get in there and measure stuff precisely.
Supercharger sound is a perfect description. :/

My whine might be slightly quieter than what is on the video, compared to the engine noise, but that sound is there. Thanks. |

Personally, I kinda like the new gear whine because it helps me imagine I'm driving a WEC LMP1 car Last edited by vfrqqq; 07-26-2021 at 10:35 AM. |
