Hello all from Wisconsin, I have a 2012 Toyota Rav4 4wd 4cyl with ongoing trans whining issues. After 2 remfg Transmissions & a transaxle/transfer case replacement,still whines at 20-25 mph and at 40-45 mph. Engineer from Toyota to meet with me Monday to tell me that it is within specs ! Don't know really what I can do about it. Thanks for your time. Joined here to see what has been going on regarding these problems.
