Hey guys,

Im new to the FiST have a weird issue that has stumped both the dealer and an independent shop. Whenever the car is in 4th and pressing on the gas, it makes a whistle noise. This doesn’t happen in any other gear, even going the same speed, it is only in 4th. The whistle seems to get louder with the RPM. I’ve tried checking everywhere online and can’t find any kind of noise like it.

I don’t know if it’s an issue or not, but any insight into what I should check would be appreciated!

Here’s the noise:

In the video it sounds more like a whine. Would you say it definitely is not a whine? In my mind whine is the tranny and a whistle would be turbo or boost leak related. Idk. Spitballing here.

Hmmm maybe it is a whine. I am a bit hard of hearing. I’ve tried looking up some stuff related to a whine noise with the transmission, and found a forum that described my exact issue on a 93’ Corolla. He fixed it by filling up the transmission fluid. I think there is a bit of an oil leak on my ST, so I wonder if I am just low on the transmission fluid and if that is what’s leaking. I’ll check and report back.
