Hi Scotty, I have an intermittent whining sound only when accelerating at low speeds (~35MPH) on my 2015 Lexus RX350 FWD with 90K miles. I put a ChassisEar on all four wheels and I don't hear noise…

Hi Scotty, I have an intermittent whining sound only when accelerating at low speeds (~35MPH) on my 2015 Lexus RX350 FWD with 90K miles. I put a ChassisEar on all four wheels and I don't hear noise from a bad wheel bearing. I put a mic on the transmission and the noise does seem to radiate from or at least through the transmission. This is the same 6-speed non-CVT transmission from a Toyota Camry and I can't imagine it's bad so soon. Car shifts fine. CV joint boots look good. What else should I check? Thanks

Make dadgum sure you install Toyota (or Lexus) OEM fluid. And double-check the grade, too. Before you DIY install the new fluid.

Thanks @ScottyKilmer. Would you do multiple drain & fill sessions back to back in this case? (To get it all out... My friend only gets a few quarts out of his Camry when draining)

change the fluid, see if noise abates. Some can make noise for years but still work
