A10 subtle whine

DirectInjection · 03-12-2021, 03:56 AM

Whenever I accelerate I hear a subtle whine by the transmission area while inside the car. I’m new to this transmission and I wanted to know if this is normal with all the A10s? My car is a 2021 SS and has 580 miles so far. Thanks in advance.

Yep, this is normal. Mine also has a faint 'whine' at times under light acceleration. Almost sound like a HVAC blower or something, but it doesn't really sound bad, per-say. It's hard to describe, but it is a faint whine noise. But again, only under light acceleration... It goes away otherwise.

When I did research about the issue, found many people with the same thing. A few took the car to the dealer to be told it was normal and no issue.

I can't recall the last time I heard it, to be honest. Either I have tuned it out or it went away on it's own with more mileage. I will have to pay attention again next time I go out for a drive.

Yes, this was discussed here a few years ago, the A10 has this characteristic whine that some notice more than others.

The whine is there in 1,2,3,4,5,6. Pop it into 7th gear which is 1 to 1 and no more whine 7, 8, 9, 10

The A10 has more than one planetary gear sets it uses to provide the different ratios. The gear sets are probably what is making the whine.

The teeth on the gears are cut at an angle and that angle is probably straight enough to make them robust enough to handle the torque input, but yet at such an angle not to be to loud.

Does anyone remember the Muncie M22 Rock Crusher? It whines like a grain truck transmission.

Same cause, the angle the gears are cut.

The sound of strength.

Anyone ever figure out this "whine" noise or have any problems? This guy says one of the problems with the 10L80 is the idler gear fails and causes a "whine"
