Very loud noise in dash when reaching 30mph-65mph

Post by Azollity »

It doesn’t always come on but usually when I’m driving whenever I hit about 30mph it starts making a very loud blaring noise like gears grinding or something hitting a gear at very high speeds. it’s been going on for years and I can’t find the cause of it.

Besides the noise do you notice any other difference in the drivability of your car?
