My tranny was swapped today and the whine is gone. The difference is night and day. This is the car I test drove. This is the car I wanted to buy and bought. Shifting is just like new - still notchy but thats OK. But I don't hear that constant whine. Just to note - the shifter does shake in neutral but that never bothered me. The hard shifting from 1st to 2nd is also gone and the throw out bearing is super quiet. All in all I could have lived with hard shifts, a slightly noisy throw out bearing and the other stuff, but not the whine. It was really bad. This appears to be a design problem - not normal. I hope Infiniti figures it out. I don't want to replace my tranny every 10k - even if its under warranty.
