All vibration is gone in 4th. I think they said it was a shifting fork that was out of tolerance.
Can you share anymore details or the reciept for the work etc. From my recent research this is one of the only cases that's been fully resolved.

I understand a car company might not get something perfect but it's how they come to plate with the fix that makes the difference.

Would love to hear more details on this. You seem to be the only one that got this issue fixed. Please share.

Any update on this? I've noticed that when shifting from 3 to 4, if you make some movement in neutral side to side it sometimes remedies the issue. There is certainly something not lining up correctly, I sometimes have the issue and sometimes it is completely gone and the gear is fully engaged. To add to everyone's dealership qualms, I went to a dealer and they did not acknowledge the issue, said they checked the AWD system and said everything is fine, also claimed it's due to the linkage style shifter on a WRX. Horrible Subaru dealer / "shop".

Default Same Issue in a 2019 WRX w/ STI short shifter

I am having the same vibration in 4th gear in a 2019 WRX with the STI short shifter. There is virtually no vibration in any other gear at any RPM. In 4th gear, between 2500 and 3500 RPM when accelerating the shifter vibrates pretty bad. At times it vibrates so much i can hear it rattling. Below 2500 and above 3500 and there is virtually no vibration. I contacted Subaru and they said they have never heard of the issue in a 2019...not that they hadn't head of the issue. I have a free oil change coming up soon at the dealer so i will ask them to take a look. I have the COBB stage 1 drivetrain package installed so i am concerned they are going to blame everything on that. I believe there would be issues in more than a very specific RPM range of a single gear if the COBB parts were to blame.

I have a friend that is a tech at a subaru dealership. He is looking into it. When I find the solution I will be posting it everywhere. I have found a few forums where people got it fixed, but no one will reply when asked about it.

I have noticed the same thing, that a slight amount of lateral movement can sometimes stop the vibration. Also that slight forward movement of the lever can accomplish the same thing, but neither movement works all the time. I don't like the idea of forward movement, as that's directly in a direction to disengage 4th, but taking the two movement solutions together may shed some light on what's going on.

This vibration, which has never been visible or audible in our '19 Limited, has always been something that could be felt in 4th, and on rare occasion 3rd (typically while investigating the 4th gear issue to see if it showed up anywhere else). Both my wife and I have noticed it (I think she was the first to notice it). We did note it as something for service to check when taking the car in for a sound system issue, but didn't get any solution or satisfaction concerning this issue.

Now before the "you're not doing it right" crowd chimes in, this vibration is something that you can detect with a very light fingertip touch where you aren't holding or moving the lever at all. If you're paying enough attention while you are about to make a shift out of 4th you can feel this little buzz as you're going through the process of grabbing the gearshift knob before you're actually moving the lever at all.

I've been driving stick-shift transmission cars since 1963, and almost exclusively stick-shift since 1972. This model WRX is the only car in all that time where shifter vibration has been noticeable.

This tells me that something along the cable line is contacting a vibrating surface when in 4th.
I'm wondering if it could be more involved than just that. Seems to me if it was that simple that a change in just that one cable that's under compression in 4th might have fixed things.

What I'm thinking is that the other cable is in a condition of little or no tension or compression because 3-4 is the gate that the shifter naturally seeks.

Has anybody noticed whether the vibration at the shift knob is mostly fore-aft in nature or mostly lateral? Knowing which might help point to where the problem lies.


Unfortunately, it appears you can't disassemble the shifter assembly. Otherwise, there might be something you could do, like an easy way of introducing a little friction at the pivot to help damp out the vibrations going up the lever. Looking for a fix here, whether Subaru-approved or not (old hotrodder attitude).
