HELLO, I HAVE A 2007 RAV 4 SX6 V6 WHICH WHEN PURCHASEDTHROUGH A SYDNEY DEALERSHIP IN DECEMBER 2011 HAD TRAVELLED 39,000KMS AND WAS SOLD WITH A 3 MONTHS/5000KM STATUTORY WARRANTY. IT WAS IMMEDIATELY EVIDENT THAT THIS VEHICLE HAD A PRONOUNCED TRANSMISSION WHINE FROM SAY 40 KPH AND ABOVE. ULTIMATELY IT WENT TO TERRY SHIELDS TOYOTA AT PARRAMATTA,SYDNEY(TOYOTAS PREFERED TRANSMISSION SPECIALISTS) AND THEY HAD IT FOR 4 DAYS AND THEY REMOVED THE TRANSMISSION AND FITTED A REPLACEMENT, MODIFIED FINAL DRIVE GEAR ASSEMBLY UNDER WARRANTY. THIS REPAIR TOTALLY ELIMINATED THE NOISE. I HAD A LOOK AT THE REPLACED GEAR SET AND THE MECHANIC EXPLAINED TO ME THAT THE PROBLEM WAS THAT THE ORIGINAL ANGLE OF THE GEAR CUT WAS INCORRECT AND HAD TO BE MODIFIED.(ALL V6 RAV4'S MADE THIS NOISE FROM NEW!) THEY USED GEAR ASSEMBLY (UNDERDRIVE) PART NUMBER 3430042080;GEAR DIFF RING 4122142120; BEARINGS A805 AND A600 AS WELL AS SEALANT AND AUTO OIL. TERRY SHIELDS WERE MOST HELPFUL AND OBVIOUSLY KNEW OF THE PROBLEM FROM PREVIOUS PAST EXPERIENCE. IT WAS SUGGESTED TO ME THAT IF THIS REPAIR WAS CARRIED OUT WITHOUT WARRANTY IT WOULD HAVE COST IN THE VICINITY OF $5,500 PARTS AND LABOUR. SIX MONTHS LATER AND THE TRANSMISSION IS PERFECTLY QUIET. REGARDS
