Unhappy Chatter upon engagement of gears 2,3,4

Problems:

1) Gearbox chatter as I shift from 1 -> 2 (as in the movement of gear knob from 1 to 2 clutch in, I get a chatter sound emanating from the gearbox)

2) Gearbox chatter as I engage gears 2, 3, 4 at approx 3000 - 4000 rpm.

- Problem occurs during upshift & downshift

Relevant info(?)

- 3400 km on odometer
- Jan delivery

- Took it to the Subaru Service Center. They say it's still bedding in and have filed a technical report about the issue.

Has anyone had this problem? If so, how was the problem fixed?

Just checked the TSB/Recall Sticky, no mention of gearbox chatter.

Went to the List of Problems Sticky and found the Sychros thread which seems relevant. There isn't a TSB as such but a change in fluid as some guys here suggest. From what I have read, it's worked for some and not for others.....still a gremlin if you ask me.

This post says it's normal:

This thread suggests that trans fluid needs to be changes:

This post states that GL-4 oil can cause reliability issues due to additional additives compared to GL-3 oil:

This post suggests that the problem goes away after 10k miles:

There is no single solution people agree upon.

The TSB you are looking for is a Toyota TSB

Noticed chatter a lot especially when I'm slowing down to a stop. Usually in free right before I stop completely, and that's when it happens.

Stupid question but is the Toyota TSB applicable to the BRZ? I noticed separate TSB for Subaru and Toyota regarding tail light condensation
