Is it at a high speed on the Highway or just normal driving any gear. If it's around 70-85mph then it's the seal above the windshield. It went away on mine eventually. Push out on the windshield at the top when the noise happens and it should go away. If it's a whine in any gear it's usually the tranny. Considered normal in other wards but you may wanna check your tranny fluid level and make sure you aren't low.My type-s is making a whistling sound and i think its coming from the trans it only happens when the rpm is around 4.5-5k anything under that u cant really hear it.. any ideas of it is?
