Whining sound on my xB 2012 109k miles

Asked by Thai Feb 24, 2017 at 01:12 AM about the 2012 Scion xB

Question type: Maintenance & Repair

Hello everyone, I am new to the forum and new to scion cars too. I bought
my scion 2012 xB on November last year from Toyota dealer and it has 109k
miles on it. So far everything is good but there are two things that make me
annoyed
1. The car is not gas efficient. I have to fill up my tank at around 230 miles.
2. There is a whining sound when i accelerate my car. It sounds like
supercharge, not to loud but annoying to me. I look through the posts here
but can not find out whats wrong with it. I will attack the record of the sound
belowhttps://drive.google.com/file/d/0B-K...ljbjhmYjA/view
Please let me know if you have the same sound as mine
Thank you
​​​​​ P/s : this guy has exactly the same whining sound as mine

Depending on whether you have an automatic or manual transmission you should try to flush or transmission or if you have a manual replaced the gear fluid with 75W 90 synthetic gear oil that fixed my problem simply a transmission wine under light loads.
