Hi guys

First post here and I hope you can help me. Went with my car a couple of days ago for normal oil service(74000kms) no problems till i get there. Started earing a howling sound everytime I accelerate. Below a more compete description of what happens. Attached you can find the sound file too. (WhatsApp Video 2021-09-16 at 21.01.58.mp3)

"My observations related to the whine/high pitched hum:
1. Highly pronounced just as you start the engine., neutral.
2. Engage the transmission, the whining continues on first second and third gears.
3. By the time you are in the fourth gear, whining is less audible.
4. When the sixth, seventh gear is engaged the whining is not audible.
5. When stopped for a traffic light and transmission is in 1, whine audible, when you proceed after the light, the whining audible to gear 4.
6. After half hour of street driving whining noise level is much lower even when vehicle is stationary.
7. If you get on the highway just as you start your vehicle and on 6th 7th or 8th gear no whining.
Prior to visiting your Service Consultant, document the following observations:
1. Highest pitch occurrence on gears 1,2,3,4 and related RPM and speed.
2. Time or mileage to reduce whine or whine to be less audible."

Any input on this? Thanks in advance for help
