If anybody can help with this I'd really appreciate it! I've got an '03 wrx wagon with 88k miles on it. Completely stock transmission which has never given me any problems. Over the last 6 mos or 5k miles I began noticing a distinct whine which I think is coming from the transmission or driveline. It is a relatively low pitched whine coming from the front of the car that is speed variable. The faster I go the higher pitched the whine (but not really louder), it is actually more noticeable the slower I go because there is less engine and wind noise. It disappears when I am almost stopped. Interestingly it is only noticeable after I've been driving for 10-15 minutes and the engine/transmission are warm. Once the car is warm it is continuous until it cools down again. It is definitely not engine or rpm related and does not change whether I have the car in gear or not. I have not noticed any change in shifting or performance of any kind. It's been awhile since I changed the transmission oil, about 30k. I checked the level and it's fine, but I'm planning on changing it in the next few days. I've been running 2 qts of redline 75W90NS and 1.8 qts of Redline MT-90 for the last 70k miles with excellent results. Anyone have any ideas? Thanks!
