 I have just purchased my new limited rav 4 6cylinder about 2 weeks ago.  I love having this SUV but I do hear a very annoying noise when i drive between 38-40. It sounds like a high pitched ringing noise.  Has anyone else noticed this problem with their rav?  I seem to think it is related to the transmission.  I once owned a jetta v6 and I had the same problem with that car.  It was a complete nightmare. They had a batch of bad transmissions replaced it twice and still no good. Finally bought the car back from me but lost money.  I hope this is not the case with my rav 4 but if anyone else has noticed this sound I would love to hear from you.  Thanks
