Hi Jimmiee,
I have been searching and reading for days looking for answers or insights to my FJ transmission whine.
I recently purchased a 2011 FJ with 66k miles. I have been hearing a whining sound similar to idler pulleys but eliminated that as a cause by removing my serp belt and starting the vehicle. Whine was still there. I hear this noise very prominently while driving and it changes pitch with my RPM's. I t also occurs in Park and Neutral while revving the engine. I have owned two other Toyota Tacomas one being a 2nd Gen with the 4.0l and A750 trans and it did not sound like my FJ. My thought is it is low on fluid or the trans fluid pump is failing/working too hard. The truck shifts perfectly and has zero symptoms other than the constant whine. No leaks or anything abnormal, it looks new underneath. I have purchased an OBD2 reader and app so I can see trans temp accurately for the fluid check procedure. Do you have any other thoughts on this in your experience?
